Hello, I have a router with a PPPoE server, and some PPPoE clients connected to it. I have problems when one user try to communicate with another one on the same router.

netmap should do the same as dstnat applied to an entire subnet instead of a single address.

I read on the wiki that NAT is disabled with connection tracking disabled, so I expect the entire “NAT” section not working

gius64

Hello everyone,

I would like to redirect traffic from an IP to another, without using a dst-nat rule, because I would like to disable connection tracking on that router, as I’m using it only to have this redirect rule working.

Is there something I can do?

Thanks

I’ve just received an answer from MikroTik: Thank you for the report. There is a known problem with enabled connection tracking and fragmented packets. If OSPF packet is being fragmented, then connection tracking passes it to OSPF twice, causing an error. Currently as a workaround I can suggest to d...

Yeah, it’s a life saver for us! We incremented tower capacity on different towers with great results.

This bug is very important as I have lots of API scripts that use the "username" field.

gius64

@glus64: default on mikrotik is aes-128, most likely your devices use different length. Maybe 256, just add aes-256 in ipsec proposal. It worked previously because of security issue *) ipsec - fail ph2 negitioation when initiator proposed key length does not match proposal configuration; Thank you!...

You forgot to mention that when you add a user in user-manager the username field was named "name" before. In 6.30 its name changed in "username" . You should mention it in the changelog. Using /tool user-manager user print the username is not printed anymore :shock: Also, IPsec+...

Thank you for your answer! I'm not announcing any IP class. My provider does it for me. If the network was bridged, I could just set a public IP on a device in the network and it would work. Do you think it will work using OSPF? If I would like to give a public IP to the CPE, what I should do? Simpl...

gius64

Thank you very much tania!
Do you have any example of how to assign public IPs to final users?
It's the only thing I have to solve before implementing OSPF in my network!

I can't find this setting on wireless-fp

I'm having better performances using nstreme than using nv2 in 5GHz-AC, but nstreme disconnections are annoying!

gius64

Oh! Thank you!
What about public IPs?

gius64

Thank you very much! It works :D Now another 2 questions: 1) How can I offer to my users a public IP? I would like to have a PPPoE server on the sector, and I would like to offer public IPs I have available on my external network to a CPE. Public IPs are available on the gateway. I mean: I can set a...

I changed to nv2 and 802.11 and the speed is lower, and either is CCQ. :( I switched frequencies during the night and I found a good 80MHz channel in AC. Speed is about 220Mbps both on upload and download, which is very good, using nstreme. Using nv2 or 802.11 I can reach only 95Mbps using nv2 and 1...

What rule for DNS reflection?
Why IPs on the bridge?

SRC is needed because I NAT only users with private IP. There are users with public IP which are not natted. I can remove to-address but it seems strange to me that a NAT rule creates these problems!

Super simple configuration:

SFP1 to an ADM
Ether1 to Ether12 bridged on bridge1
Public IP on SFP1
Private IP on Ether1
NAT on IP class 10.0.0.0/8

My computer connected directly to the ADM: full speed
My computer connected to one of the port ether1-12: 20mbps max (per port!!!)

Update: Rebooting the router gave me max speed for 3 minutes... And then 20mbps

gius64

It would be great to know exactly which card you used, which antennas and so on

Thank you for your feedback!

gius64

Wow!
What card is it? Is an SXT/NetBox? How much distance? How much signal?

Can you post "Status" section? Is it a MIMO? 80MHz?

gius64

Only 215Mbps with 80Mhz bandwidth? It's not a MIMO antenna I see, right?

I had some time I thought I'd like ubnt products. But the more you work with it, the more you find it is limited and not performing to it`s promises.

gius64

Do you have interferences in that area?

gius64

Thank you for your reply!

So you have all queues on the concentrator?

gius64

Did you change pfifo queue size on all APs or only on the PPPoE concentrator?
I wrote a thread about this issue: http://forum.mikrotik.com/viewtopic.php?f=7&t=83477

In your experience, is PFIFO 50-100 better than SFQ?

Thank you!

gius64

Are you sure? I saw ping improvements...

gius64

I don't know why it makes such a big difference, and I don't know if RED is best than SFQ and in what cases... I read theory on the wiki but it shouldn't make such a big difference. It's a point for them to show how good nv2 is, but i never found an official guide from MikroTik where they talk about...

gius64

This is the answer from MikroTik: For different applications different type is best for long links PFIFO 200 it best for other RED would improve latency and speed. RED with default settings but you can tune it changing values. SFQ is default for for hardware wireless and it works good in most cases ...

gius64

I would like to understand what happens if I enable wireless-fp on the AP but not on the customers' RB... Does it work? Does it have issue or simply users won't get improvements?

gius64

In some case, with no traffic, i saw something similar to picture showed by rado3105, but not using wireless-fp. With it the latency is low and very stable.

CyberTod, did you try wireless-fp also on Ptmp?

gius64

If you can, try the new wireless-fp package on RouterOS 6.15

It solved my latency problems!

gius64

I tested it over two p2p links and it runs very well. Super stable latency with nv2 also with no traffic and almost like nstreme. One one link TCP traffic is a little bit better using nstreme (5-10mbps more TCP on 80mbps) I would like to test it also on ptmp on one or two APs and some users. What ha...

You can use API! Using PHP PEAR2 API you can do something like this: try { $client = new RouterOS\Client('YOUR_IP_HERE', 'YOUR_USERNAME_HERE', 'YOUR_PASSWORD_HERE', null, false, 5, Transmitter\NetworkStream::CRYPTO_TLS); } catch (\Exception $e) { echo $e->getMessage(); } $username = 'USERNAME_TO_REA...

I have a shielded container for RB and i put it 1m away from the sectors, attached to it with two shielded coaxial cables. So, you suggest: 1 RB => 1 Radio -> When there are competitors and there isn't clean air space 1RB => More radios => When I'm alone and there is clean air space ? Exactly where ...

gius64

The problem is this place is very uncomfortable and I would like to reduce the number of RB to the minimum. Do you know any trick to shield them better? Is using 1RB => 1 Radio the only real solution? Why is MikroTik selling routerboards with 2, 3, 4, 5 radio cards if using these slots is an issue?

gius64

Yes, they are attached to 433, i meant "two of my sectors on an AP"

If I use this and on client enable both or only horizontal polarities, does it work like using only horizontal?
I would like to use it as I have lots of clients already set on vertical polarity only!

gius64

MIMO use both vertical and horizontal, is it a problem?

gius64

Great work! It would be great if you can write a short guide on how to use it

You could also add 5GHz-120° sector antenna pattern

Thank you all guys, great feedback about your experiences!

Changing the antenna polarity in crowded locations has helped me in the past.

Change polarity is another good method to use

What about using MIMO antennas?

Why?

I never did a scan for more than 30-40s but I'm curious about this!

gius64

Sure! It's for this reason i called it remote scan :D API connection is like SSH connection, i think there isn't a real limit on timeout. If you set 60s duration and 80s timeout, it works!

You can set your wlan here:

Yeah, you're right

but I'm troubleshooting some wireless issue and i want to be sure about every single setting of my APs.

I'll keep it disabled, but if someone from Mikrotik can help to understand what does it mean exactly it would be great!
