MikroTik

johndjmix

Its very easy to do, mikrotik sells the cables. I posted a youtube video here in case anyone wants to do it.

... What happens if you replace the hAP with a laptop. Does it get the DHCP lease ? Thats how ive been testing lately, same issue. Doesnt get an ip. I should point out if i put an IP in the laptop or HAP manually, it works fine. So the only issue is its not getting DHCP. The most frustrating part i...

Just tried with pusedo-bridge-clone, still no luck. Pretty small config, here it is: /interface bridge add fast-forward=no name=bridge1 protocol-mode=none /interface list add comment=defconf name=WAN add comment=defconf name=LAN /interface wireless security-profiles set [ find default=yes ] supplica...

I really dont want the WAP to do the NAT, for the reason i want the HAp inside the coach to be the main routing device. It will have multiple ways to grab internet, the WAP is just one of them. The others are LTE, a plain ethernet to a port at my place, or via the USB port. If i do keep it as is but...

johndjmix

Guys, i posted the other day i had this working but i didnt know why. Now, no dice.....im missing something here. If you read my old thread, i had this working...but i messed somthing up. Ive literally spent days working on this with no luck. I have an RV, inside the RV is a HAP. This will provide w...

johndjmix

I got it working, not sure totally what i was missing, but i know at least one thing, i had the firewall using the params for LAN and WAN and didnt change what they related to in that one tab. Got that changed and some other small stuff and boom, got the IP from the external network. So the WAP is j...

johndjmix

Thanks for the ideas guys! For now i setup the WAP as a AP to serve the 2.4 devices. I forgot to mention, the 2.4 devices in the RV do not require any kind of high speed. They are mostly wifi light switches, and other local LAN control devices for various systems in the RV. Defiantly dont need anyth...

johndjmix

I think the question you should ask is why do you need somthing so fast? I have several datacenters, with around 100 random servers each, pulling 100 M/bit steady...each on a $500 ccr. Super fast, no complaints. CPU on the mikrotiks never breaks 50%. So unless your doing several Gb's / sec.....i can...

johndjmix

Hey guys, heres my setup. I have an RV i take to various offices and stay a few days. The RV has several devices in it that need internet. So... Ive installed a HAP in the RV, works great. Currently i have it setup to grab internet on the 2.4 interface, using a connect list, so depending what office...

johndjmix

FYI guys, got this all setup and working. And it was simple....mikrotik style =)

I LOVE mikrotik router's!

About the only complicated thing to setup in them is setting up an IPSec VPN....but thats complex no matter what device you try to set one up on.

--John

johndjmix

I would say the same thing, but im not trying to go distance...just 30-50 feet around the RV, and just with 5ghz. Would it be permissable to route the wire from one antenna to an external antenna and leave the other inside the RV? Or does the mikrotik need both in the same spot (For MiMo or similar)...

johndjmix

Do both antenna ports go to both radios? Which one is for which radio?

Installed in an high end RV, 5ghz used inside, 2.4 used to pickup wifi from outside....Would like to put an external antenna for the 2.4 outside. Just need to know which port is which.

--John

johndjmix

Is this possible? Ill explain the situation: I have an RV, everything in the RV is wireless (unfortunately they didn't run Ethernet when it was built). The RV is occasionally at one of several locations that i have private wireless (2.4 and 5) available. What i would like to do is to setup all the d...

johndjmix

Situation: I have 2 datacenters, one in NY, NY and one in Denver, CO. (Fictitious ips are used here for example purposes...) NYC: I have a cabinet of servers in NY, using 205.34.12.0/24.....this feeds into a rb1100 port5, with port 5's ip being .1 of that network. The rb1100 has port 1 plugged into ...

johndjmix

Im having the same problem. Basiclly, we need a way to untag packets on egress from a port, but NOT all packets...only the ones from a certain vlan. This seems like a very basic thing to do in the VLAN world, i dont see why this cant be enabled. I picked up 3 of these switchs to do just that (use wi...

johndjmix

Gentleman, im at wits end here. I need to remove the Vlan tag upon a certain vlan when it exits out port 5. BUT i have 2 other VLANS that need to keep their id upon exiting this port......Any ideas on how to acomplish this? I have a trunk of 4 VLANS running into port 1 of a 250GS. VLAN 50: ------> g...

johndjmix

I dont really thinnk explaining my network is necessary......(not trying to be rude of anything but we have an EXTREMELY complex network).

Simple question, is the unit reachable from a different subnet.

--John

johndjmix

Is it possible to access the interface of the RB250GS from a different subnet? Since it doesnt have a gateway, i figure no? Ive worked with a lot of the high-end mikrotik devices with routerOS (and LOVE them) but never one of these, but if it can be accessed from outside of its subnet it will be PER...

johndjmix

Ok (shrug) now I feel silly I didn't see that. Thanks

--john

johndjmix

Using routeros 5.7 on a rb1100 I hate to ask what apears to be a simple question, but ive searched everywhere with no avail! I'm trying to get my mikrotiks to log to a remote syslog server, I see where you setup a logging action, and select "remote" but where do you set the ip of the syslo...

johndjmix

Yep, I realised this. Just didnt want to have to make a 2 scripts for each interface (one for up and one for down), and change my admistration/billing system. Since most all devices support the ifadminstatus command, my mysql billing system database just holds the router host name and the interface ...

johndjmix

You can do it but it doesnt change the interface status. Here I try from a remote linux box to set the snmp for the interface up/down.....look what happens. [root@admin vb]# snmpwalk -c privatecomm -v1 core.somthing.net | grep ifAdminStatus.10 IF-MIB::ifAdminStatus.10 = INTEGER: down(2) ^^^^^Check s...

johndjmix

I really need a way to turn on and off ports via SNMP, since this is how our billing system turns customers on and off when their bill isnt paid..... Being able to do somthing like: snmpset -c privatesnmppass -v1 somerouter.somenetwork.net ifAdminStatus.11 = 1 is important to us, and is a basic SNMP...

johndjmix

That really sucks, as this is EXTREMELY important to me. Can we get someone from mikrotik to get this bug worked out???

--John

johndjmix

Spoke too soon. I think I got it sorry guys. FYI: When you have ciscos Advertising to tiks, make sure their OSPF config is as IDENTICAL as possible. The smallest difference can make one route not get into your tiks table (Yet still show the same LSA info so you will be stumped). Basiclly what seemed...

johndjmix

Happening again, IDENTICAL LSA's for both defaults, but only 1 is getting installed. Dont get this intermittent problem...

--John

johndjmix

Upgaded the 2 1100's to 5.7 (They were at 5.4). So far so good, they are seeing both borders....

We will see if this keeps up -))

You going to mum in Vegas fewi? I definatly owe you a few beers...

--John

johndjmix

Running 5.4 on the ones with the issue.... Didnt look till just now, but the one running 5.5 is actually working properly....so I think you might be right fewi. Output from the 5.5 mikrotik: [admin@core1] /ip route> pri detail Flags: X - disabled, A - active, D - dynamic, C - connect, S - static, r ...

johndjmix

fewi, ok...so im not nuts here. Possible mikrotik bug? Defiantly not seeing both: [admin@core3] /ip route> print detail Flags: X - disabled, A - active, D - dynamic, C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme, B - blackhole, U - unreachable, P - prohibit 0 ADo dst-address=0.0.0.0/0...

johndjmix

Well, currently its taking the "xxx.xxx.xxx.2" route, and the cost of that is "1". I cant really test dropping that till Thursday when ill be at the site in NY......will let you know then.

--John

johndjmix

This is one of those "works sometimes then stops working" things. Basically, have 2 border routers (ciscos) talking OSPF with my cores (Mikrotik's)..... The mikrotiks see the OSPF routes to 0.0.0.0 from both borders in LSA at all times, and when you look at the LSA details for each EVERYTH...

johndjmix

Since replacing our core routers with mikrotik our level of support has been amazing to our customers. Everyone loves what we are able to do with the mikrotiks! Im considering replacing one of my border routers, a cisco, with a RB1100 or RB1000..... Anyone out there running BGP with full routes two ...

johndjmix

artie11: 4 or 5 days i also thought was impossible. But that little tropical storm that just came through NY had me running my facility off the generator for almost 2 days. Some people still dont have power and its been 4 days! This was not a devistating storm, it did little damage and wind speeds w...

johndjmix

So you run the tik OS off the HD? Thats the one thing I dont like. Even though newer HD's rarely fail, I would feel better running off some sort of solid state media.

--John

johndjmix

Really, every day that goes by we find another reason to love the mikrotiks more. We have 3 RB1100's now, and a 750G. LOVE THEM. They are doing well, but I can see a need for more CPU power in the near future. We run them in a datacenter environment that's pushing around 100 M/bit steady traffic. Is...

johndjmix

Good tip blake...

--John

johndjmix

I think I solved the problem. Something kept bothering me about the forwarding address being in one but not the other. I did some research about that and found that by default a cisco has OSPF enabled on ALL interfaces when you enable OSPF. You then need to turn off the ones you dont want it on. Sin...

johndjmix

Just shot them an email. fewi, if you keep answering my questions im going to have to put you on the payroll!

--John

johndjmix

Started a new topic since this was getting off-topic from my BGP post. I have 3 core routers, all mikrotik, and 2 border routers, both cisco 7000 series. Running OSPF internally, BGP externally and IBGP Between the borders. Now on to the problem... (Any ips here are fictitious) Both borders advertis...

johndjmix

Unless im doing something really wrong, it seems the ifAdminStatus var (via SNMP) isnt writable. I use snmp to turn on and off customer ports via our billing system, so being able to write to that var is necessary. I know I could write a script to do it, but that would mean 24 scripts (2 for each po...

johndjmix

fewi: Got the setup complete tonight on my test network. Shut one of the border routers off. About 2.5 minutes later, my test machine was back online. Worked perfectly! Thanks a million times man. Both tik's are seeing 2 defaults (Dont really know what that started working but it did. If you ever ne...

johndjmix

Took a look at it, both the ciscos pointing to the core (mikrotik) are configured the same: router ospf 1 router-id 202.xxx.xx.1 log-adjacency-changes network 0.0.0.0 255.255.255.255 area 0 default-information originate router ospf 1 router-id 202.xxx.xx.2 log-adjacency-changes network 0.0.0.0 255.2...

johndjmix

fewi, want a job? In sunny NY? -))

Thanks again!

--John

johndjmix

Ahh, got ya. Any idea on how to allow the mikrotik to accept 2 default routes...i.e. my borders are both advertising a default but the OSPF on the mikrotik seems to just use one, i was hoping i could get both to pop in there....

Or do I need to use 'mangle" to accomplish this?

--John

johndjmix

external routes? External to what....as in a different OSPF area?

--John

johndjmix

Has this memory leak issue been resolved?

--John

johndjmix

Hi, im trying to setup a route filter to allow only a default route to flow into my mikrotik from ospf: #accept default route add chain=ospf_only_def_in prefix=0.0.0.0/0 action=accept #discard the rest add chain=ospf_only_def_in action=discard Then I set this as the in-filter in the OSPF instance. I...

johndjmix

Thanks man, i appreciate the help. Ill update the thread next week when i start setting this up.

--John

johndjmix

Wouldnt have to worry about customer reboots causing OSPF--->BGP changes, since i hand out the network on the mikrotiks, with the tik as their default gw. So unless my core reboots nothing would change... I see whtat you are saying. Since the borders are running ibgp...if one suddenly loses its inte...

johndjmix

fewi, thanks for the advice. Im going to set up a test next week to give it all a shot.

--John

johndjmix

Please see the attached Image of the proposed new network map. All IP's are ficticious....Right now we are running basiclly the same map, but with only 1 border router. We are adding a second border to take load off the first and, most importantly, protect against failure of one of the border router...

johndjmix

Heres the situation. I have a hotspot interface going on a ethernet bridged to a wireless radio on my tower, which i use to provide service to clients. Normally I set the CPE (Ubiquity) to router mode and let it do NAT, that way the customer is seperated from the bridged network and cant step on any...

johndjmix

Of course, after hours of work trying to figure it out....i post, then 10 mins later I get it. For anyone else that has this problem, its as simple as adding a binding:

Just add the MAC and the address of the unit....leave to address blank.

That should do it.

--John

johndjmix

Basically what i have here is a 450G connected to my backbone Eth1 i have a local network for customers in my building set on hot spot - works perfect. Eth2: This goes up to the roof, where it hits a hub and goes to my ubiquiti Rockets..... The rockets are on xxx.xxx.71.227, xxx.xxx.71.228, xxx.xxx....

johndjmix

Well, u guys make me feel more confident at least. I have a 1.5 mile link in NY im going to be setting up next week that im worried about, sure makes me feel better when u guys are complaining about issues going 26 miles! lol!!!

--John

johndjmix

Actually that would be kinda cool .lol.

johndjmix

Got cha. Read the wiki just now. So all the posts i read to that refer to "chains" are refering to a single antenna vs dual antenna's?

~john

johndjmix

Didnt get the cards yet, just noticed the dual connectors. Ok, so with the N cards what is the purpose of the dual connectors? I assume for using 2 antenna's (One for transmit one for recieve)? Or is it possible to aim one antenna one direction for coverage of one area and aim the other another dire...

johndjmix

Hi, im getting ready to setup a 1.5 mile PTP connection. I have purchased a few alfa 2000mw usb adapters with 19dbi panel antenna's for a quick cheap way to test the connectivity before installing mikrotik's. We currently use mikrotik for internal non-wireless routing now, and they work great. Can't...
