[SOLVED] RB 1200 initial setup

Hardware MikroTik hardware general
1

Can’t connect to my RB 1200. Just installed it, connected Ethernet cable to eth1 port, configured client address as 192.168.88.2.
Can see neighbor discovery packets on the interface but no reply to arp requests.
Here is tcpdump output on client interface:

# tcpdump -i eth3 -nn -l
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

Do I miss something?

Are you plugging into the last port on the router ?
Have you tried MAC access via Winbox ?

3

Try connecting to another port

4

Most routerboards have eth 1 configured as a gateway interface by default and do not allow you to ping or use routerboard to connect to the management. Please try a different port and see if that works better.

If ping and 192.168.88.1 do not work on the other ports either. Try connecting using the MAC method (little dots in winbox, click the mac address if it appears) or otherwise resetting the RB1200 and see if it comes up then.

Thanks everyone for the answers.

djdrastic,
There are 10 Gigabit ports, from eth1 to eth10, in manual it is written that eth1 is configured as 192.168.88.1. Should I use eth10?
There is no Windows there at the moment, can’t try winbox now.

nickshore,
I’ve also tried to use eth2 port, but the picture is the same: port is alive (I can see udp port 5678 traffic), but can’t get ARP reply for the 192.168.88.1 request.

Quindor,
yes, I’ve tried eth2 and have no Windows there at the moment.


P.S. may be there is some strict manual about initial connect to not configured RouterBoard 1200 (just saw that it is mentioned about port eth1 and address 192.168.88.1 here in Quick Guide http://routerboard.com/pdf/304/rb1200mA.pdf ) ?

@mikrotikuserm , it’s worth a shot . I remember having a similar problem once and had to run through all the ports until I got joy our of the last port.If all else fails like mentioned , try a MAC winbox session.

Have you made sure there is nothing like a software firewall/antivirus blocking the machine you are trying to connect from ?

Whist it does physically have 10 Supposedly Gigabit ports it’s actually more like 8 Ports plus 2 that might work if it’s a blue moon and the wind happens to be blowing in the right direction.

I’ve yet to see anyone report that the problem with the drivers for these ports has been fixed.

Sorry for the delay, my mikrotik is not in the office, couldn’t try your suggestions immediately.

It turned out that 192.168.88.1 ip address was configured not on eth1 port but on eth10.

I have no idea why hardware developers do such things.

you can always check what is set up as default by doing ‘/system reset-configuration’

at least in configuration script IP address is set to ether1 Check if ethernet names are in correct order
