Hello everybody! I have got a site to site tunnel only for learning purpose. Mikrotik have dynamic public IP, Debian have fix. There are four private networks behind Mikrotik, but when the IP change one of the SA Src Address is stuck at the previous one in the particular Policy, and the problem is a...

Trackboy

Note that this setup is only viable when one side is behind NAT. Otherwise you can specify DNS directly in GRE settings with ipsec-secret starting from 6.45.1. The bridge on server side acts like a loopback interface on which the internal address is configured used for GRE tunnel communication. If ...

Trackboy, the first thing i did, which really helped, was to use Ping with the DF flag set to discover the actual MTU that gets through. perhaps try that and see if you are getting the same max packet size in Windows and Linux?

Trackboy

Hey

I would suggest to copy your current config, and then reset to default configuration, and then only selectively add some rules. The default config is "compatible" with vpns, and I think will be the easiest route.

I will give it a try today, with my old 750GL. Thank you for the hint.

Trackboy

No, it does not. I know the L2TP, In case of L2TP RouterOS creates an interface, but in IKEv2 does not.

Trackboy

L2TP ? But i use IKEv2 now

Trackboy

I tried lot of MTU, but i could not find the proper value. I tried L2TP/IPSec solution and that is working fine and assign public IP.

Trackboy

I tried several MTU-s so far, but the problem is the same. If i want to ping a host that is working fine, there is not packet loss. On the speedtest.net i get 100/100 Mbit/sec.
So the web browsing is very slow.

Trackboy

My PPPoE connection shows now 1480 MTU and MRU. I set this value on the both side in the IPIP configuration. But the problem is the same.

Trackboy

One more question. I have got a PPPoE connection with dynamic IP. I tried the tunnel with this connection. The speed was around 2-3 Mbit/sec. The ping is perfect and i do not have packet loss. Maybe i have got MTU issue, and i would need to change with the mangle. I have got another connection with ...

Trackboy

I tried with IPIP tunnel, working very well. Thank you very much for your help and your patient : ) This is really helpful and valuable for me.

Trackboy

It should work with GRE too ?

Trackboy

So i have got a GRE tunnel that is working fine between the CHR and home Mikrotik. On the CHR there is only one ether1 interface with 2 public IP addresses: 217.144.X.X/24, of course they are from the same range. I added only 217.144.X.119/24 to ether1. Mikrotik GRE interface IP address: 172.16.1.1/...

Trackboy

I made an encrypted GRE tunnel with the IPsec secret feature. 172.16.1.0/30 is the GRE tunnel ip range.
On CHR added 10.10.100.0/24 route, this is behind the 951G. That's it.

Trackboy

I made a GRE tunnel between the 951G and CHR. The tunnel is working. I added routing mark too.
I added public IP to my server statically. But does not work. I can not find proxy arp feature in the GRE interface.

Trackboy

Thank you very much for the help, i will give it a try : )

Trackboy

I would rather make a tunnel between them, and i would like to assign the IP to the server statically.
Maybe EoIP tunnel would be good for this ?

Trackboy

Hello everybody! I have got a Mikrotik CHR with 2 public IP addresses. I would like to assign one of the IP address to my server.
My server is at home, so i would need a tunnel that capable of this thing. So is there any solution for this ?

Thank you very much for any help!

So nobody know ?

Hi,

Do you mean the ap has 2 chains enabled with a dual chain antenna and then you connect a mixture of cpe's to it sxt(2chain) rb groove(1 chain) ?

Is so then it won't be a problem

Yes, exactly i mean this way, thank you anyway.

Trackboy

Hello everybody. I would have a question. Can damage the AP if we use 1 and 2 chains client simultaneously ?
Sure both of the chains enabled in the AP.

Thank you in advanced.

Trackboy

I read about 100 Mbit/sec with 802.11 AC with 20 Mhz channel width. So you should get at least this speed or more on 2 km. You can play with the settings. First you need to achieve good signal strenght. Around -50 and between -60 dBm. Your signal strenght is too much. This 29 dBi antenna is good but...

Trackboy

Hello. Your signal strenght should be -50 and -60dBm and your signal to noise value is huge.

Trackboy

I think if the fresnel zone is 100% clear and the environment is less noisy, the sxt will be fine for 2-3 km.
So i think you would need something else.
Depending on the budget.

433AH is a strong device. Are you using 802.11 N ?

Trackboy

I do not know Kenbotong, it is similar like other dishes, 32 dBi, so should be good for this distance.

I think a new 802.11 ac link with 20Mhz channel bandwith should be ok.

But you know, this is...

Trackboy

Hello, i have never done this link like this before, but you need 100% freshnel zone.
How much bandwith do you need ?

Trackboy

Try this one, Bootp support: disabled.

Trackboy

Your CCQ is not someting good, it is should be 90-100%. Have you tried other channels ?

Trackboy

So do you have 40 clients, and would you like to provide for them 10Mbit/sec ?

Trackboy

I am very curious what speed capable of this equipment on 12 km.
My experience is that in point point backbone network needs to achieve at least -60dBm signal strenght.

Trackboy

You need to NAT only on your router, that is connected to the ISP.

951G and 411GL are powerful devices, so that's why i achieved 200 Mbit/sec.
I do not remember exactly 951G's switch performance, but that was around 300 Mbit/sec with Proftp.
I have never tested with internal bandwith test.

Trackboy

Hello, it is fixed, thank you very much for your help.

I tried with 24 V 0.38 A, at the moment working for 10 hours with 12V 0.5A, but very interested this kind of problem because before 6.15 everything worked fine.The problem is the same, i tried with 3 different 12 and 24 V power supply.

Nobody met this kind of problem ?

Trackboy

I have got a problem with 6.15. 411GL with R52Hn and R52n-M every 30 minutes or 1 hour just suddenly stopped.
Then i plugged off and back, working 30 minutes or maximum 1 hour.
I have got another 411GL and 6.15 running smoothly.

Trackboy

30 megabyte or 30 Mbit/sec ?

Trackboy

I have never tried

Trackboy

According to calculator: 55 km, -62 dBm

Equipment: DBii F50N-Pro Mini PCI, Rocket Dish 32-34 dBi

Trackboy

I think -60-70 dBm is the perfect signal strenght, and the SNR is 30-40 dB.

Trackboy

I tried with new 6.14 and with new wireless package, the speed is the same.
But i think this is perfect.

Trackboy

I will try out

Trackboy

What is wireless-fp package ?

Trackboy

Here is my test result, i achieved this performance in my room, but i think this is very nice performance:
There is a wireless connection between the devices, and running OSPF between them.
Proftp running on my Ubuntu 12.04 server, so this speed is 158 Mbit/sec TCP speed, and CPU load is around 60%.

Trackboy

I know very well, i am just curious, the target is 130 Mbit/sec TCP speed.Of course it is will work only with 40Mhz channel width.

Trackboy

It is depending on your required bandwith, i have got an 1 km Sxt-Lite5 link in a very noisy environment, signal strenght around is -60dBm, but the speed is very fluctuating, i have never reached stable speed so far with internal Proftp server that is running on Ubuntu 12.04. I am sure in less noise...

Trackboy

Hello, is this antenna dual chain ?

Trackboy

Yes, this is a cheap device, and working fine, just more than 3 km is too much to me from this device

Trackboy

3-8 km not too much for SXT ?

I have got a 1km link with them, the signal strenght is around -60-65 dBm.

According to calculator 2-3 km is the maximum with SXT, but i think for this distance perfect.

Trackboy

And what's like the signal strenght,CCQ now ? and the speed ? I am just curious

Trackboy

The RX sensitivity should be the same on both side, if you want to build a backbone network, you should use the same devices on both side, this is my advice

A point: bridge
B point: station-bridge

The signal is to match on -41 dB the signal can disturb itselfs. -60 dB is good and normal. Yes, i have got an SXT-Lite5 1 km link, the signal strenght is around -60dBm, but i can not use 802.11 N in this town, because the local WISP using every channel, but for 2-3 km the sxt should be good, if th...

Yes need to align perfectly, i know, here is another one interesting thread:

http://forum.mikrotik.com/viewtopic.php?f=7&t=60932

Trackboy

Nice performance, we are planning to start an WISP, so not impossible to achive the 100 Mbit/sec, anyway i counted with Rocket Dish 32-34 dBi and Dbii cards around -52 dBm signal strenght on 22.43 km, but this is just theory

Trackboy

Nice, and what is the tcp speed of this link?

Trackboy

The first link is 22,43 km, and i heard about the Dbii F50N-PRO card is very good card, 20 dBm tx-power for 40 Mhz at MCS7 and the receiver sensitivity is -77dBm,but we should achive at least -65 dBm signal strenght with 28-30 dBi dual chain Rocket dish, but i am afraid that it is won't be enough, w...

Trackboy

Hello everybody, 54 km with Sxt, it is definitely impossible to me, anyway i tried to ask in other thread some similar long range links: 22,43 and 30 km but we would like to get 100 Mbit/sec tcp speed in one direction.I have got RB 411 GL it is a powerful device with 680 Mhz CPU and 64 MB Ram, and i...

Trackboy

But it is can damage the card if i good remember, but it is working very well,the signal strenght is about -60dBm,thank you for your help

Trackboy

Hello everybody!In my RB 951 i can not set to the "card-rates" option.This error has appeared:"Could not change Interface wlan1,not supported tx-power mode. I am using ROS 6.7. This device has a strong Wifi, and i need to set the Tx-power about 5 dBm

Trackboy

I read here on this forum 70 Mbit/sec TCP speed with 30 dBi Grid antennas on 11km, 31 km is definitely too much,that's why asked the plan is achiveve the 80 Mbit/sec?Maybe with dual chain antenna and properly CPU performance it is possible.

Trackboy

I can not draw a picture,but here is the scenario: RB 751--------------RB951 they are the OSPF backbone. RB 751 ether1 connected to the ISP:192.168.1.195/24 and the dns is:192.168.1.1 At the moment there is not any area that connected to the backbone. Anyway i took your advice:at the moment i need t...

Trackboy

Hello,so i try out without areas, at the moment the backbone network is:10.10.10.0/24 RB 751:10.10.10.1/24=Ether3, and there is dhcp-client on Ether1 interface=192.168.1.195/24, dns-server is:192.168.1.1 RB 951:10.10.10.2/24=Ether1 On RB 751 enabled: redistribute-connected routes=as-type 1 and redis...

Trackboy

If this is an Point-Point backbone network,why are you using wds?I think you should try out this setup:

A point:mode:bridge
B point:mode:station-bridge

And maybe you should try out with Nv2 as well.

And what's like the line of sight,and the freshnel zone is clear? Because 31 kms is very long range.

Trackboy

So nobody knows why need to NAT the backbone and the area networks?Why not enough just the connected networks?

Trackboy

may i have a question? 80 Mbit/sec or 80 MB/sec? I am very beginner in the networks, but this is interesting for me My friend and me would like to start an wireless ISP, and the distance almost the same in our case as well. The distance is 22,43 km, and we are planning 100/50 Mbit/sec maximum TCP tr...

Trackboy

Yes,the default routes are correct,and my next question is that how should i set the NAT correctly? The internet is working,i can connect from the connected networks for example,with my LG phone I need to redsitribute the default route on my 751,because this is working now as AS router. And all rout...

Trackboy

The default route redistribute has enabled on all devices,but i still can not connect to the internet

Hello everybody!I can get an 192.168.1.195/24 IP address from the ISP,this is an inside address.DNS server:192.168.1.1,Gateway:192.168.1.1 This is appear in my RB 751U on the Ether1,this is an dhcp-client.On this port i can get internet connection. On the Ether3 port running the ospf backbone networ...

Trackboy

At the moment the RB 411U and RB411GL between there is 1 km wireless link,and via this link my friend give me Internet connection,and if i good think this would be an OSPF backbone area,and my home's LAN is for example area1,1 more question:is there more backbone networks in one AS system?

Trackboy

Yes, i know,but my friend RB2011 and the 411U and 411GL are not running the ospf,i am not an expert,i am learning now,how is working in the real life

In this example anyway my R1 i...

Trackboy

I have 200mbps real speed link on 35km
i used 36dbi 5Ghz antenna on each side Dual pol MIMO+R52Hnd+RB800

This result is TCP speed?

Trackboy

So what do you think,if the freshnel zone is clear what is the expectable TCP speed with these equipments on 32 km?

Trackboy

The towers are 50 meters

Trackboy

Hello everybody!We are planning an almost 32 km link,and we need some opinion about equipments,we need 50/25 Mbit/sec TCP speed,we are thinking an Rocket Dish 34 dBi,RB800,Dbii 5 Ghz miniPCI,the LOS is enough good

Trackboy

On 2,4 GHZ or 5 ?

Trackboy

Hello,i am interesting about speedtest on 5 km distance,i mean between 2 sxt,i think the 5 km is the maximum distance in normal case if the freshnel is perfect and not too noisy the area, thank you very much for your help,but 50 Mbit/sec TCP speed not bad from this device if it is possible to achiev...

Trackboy

Yes i know,because i think an sxt enough for 1 km,and in normal conditions, it should be work properly,we planning to buy,because the price is good,600 Mhz,64 MB Ram,but it has got just 100 Mbit/sec Ethernet port

Trackboy

Hello everybody!I am planning to buy a new Sxt Lite5,the distance is 1 km,we would like to connect 2 LAN networks,and testing,learning some things,one of my friend said to me,he is working for a WISP at the moment,and they tested this new sxt,and the results was terrible on 200 meters,the signal str...

Trackboy

I could achieved,only 40 Mbit/sec TCP speed,i tried with FTP,but without Nv2,my Samsung laptop support 150 Mbit/sec with 40 Mhz channel bandwith

Trackboy

I am curious,this device capable of 100 Mbit/sec TCP speed,but it has got only 400 Mhz CPU

Trackboy

I need ap bridge mode

Hello everybody,i noticed one thing about this card:i am using this card on 5 Ghz backbone link with Nv2,with default Tx power,but the Tx power value is not same than in the card of pdf,Mikrotik says that: 802.11n 5 Ghz: MCS7 40 Mhz:13 dBm Tx power But in the winbox show me only 10 dBm Tx power for ...

Trackboy

Ok,we found the problem,411 GL Ethernet port is not working properly,i have to send back to the store,where i purchased,411 U RB capable of 62/Mbit sec TCP speed with this grid antennas

Trackboy

Ok,seems to be the 80 meters utp cable on ap side between RB2011 and RB 411 GL,not ok,TCP speed only 13-14 Mbit sec,we have to change

So the 411 GL capable of 100 Mbit/sec TCP speed?(50/50 Mbit/sec?)

But with the new Mikrotik mini PCI card the experience is not something good?

Trackboy

Ok,i will test nstreme with UDP,with 20 TCP count the speedtest result is same

Trackboy

Ok,here is the picture,the result is same with 20 TCP count too

Trackboy

The place inline is does not appear for me

How can i insert here picture?Sorry for my bad english

Trackboy

Thank you very much for your answers,we are beginner in Mikrotik devices,but this link is properly for learning.

At this moment we don't want to buy another devices,maybe later.We assume the Mikrotik's Bandwith measure is not correct

Trackboy

So,this is sure interference problem,we are planning later 20km link with these devices,what do you think?What is the expectable bandwith from this kit?
