RouterOS x86 isn't routing

RouterOS Beginner Basics
1

I’m having some trouble with our x86 main router.

We had to switch service providers, so we had to have new IP’s. I changed the ip address of the outgoing interface and changed the gateway to reflect this, and all routing has stopped completely.

ether1 = 192.168.0.202
ether2 = 172.20.101.1

gateway = 192.168.0.1 on the ether1 interface

This is how it’s setup, but it just isn’t routing at all.

edit: I’m able to ping everything on the 172.20.101.0 network from the router, and ping everything on the 192.168.0.0 network, including everything on the internet.

Does that mean your problem is solved?

no, I can ping Ip’s from each interface, from within the router’s cli. I cannot, however; ping or connect to anything from one interface to something on the other. Basically, the router is not routing across it’s own interfaces.

the only way i could get it to work was to hook up a less powerful consumer level router and have it give out a dhcp ip address to the mikrotik router so all the routes would be dynamically assigned. This doesn’t do well for speed though. And DNS requests get dropped all the time for some reason.

I encountered the same problem after switching providers once.
Everything was configured correctly, but it just wouldn’t browse. I had to reset and reconfigure my router. Loaded my rsc backup files and i was back online.
I guess these things happen!

that is not reassuring at all. thanks for the info.

If you are using NAT, check if those rules are correct.

Yep, sounds like some little check box or small issue. I would suggest getting a Mikrotik consultant to take a look at the box. http://www.mikrotik.com/consultants.html is a listing :slight_smile:
