Double Internet Gateway

Tue Oct 19, 2010 4:51 pm

Hi to all,
I would implement a redundant gateway in my routeros.
In particular consider that I have a RouterBoard with 3 interfaces: eth0, eth1 and eth2

eth0 and eth1 have different internet link, while eth2 is the ethernet interface connected to my lan.

I would to use eth0 as primary link to internet and gateway for my lan, but if link is down I would that router switch automatically on eth1.

In which way Can I implement this one?

Add two default gateways with check-gateway=ping, and one with greater distance. If primary fails then other one with greater distance will become active.

There are also other examples that may be useful:

But "check ping" would only check for gateway interface, not for ISP connection....

So, if my ADSL modem ( is up but without internet connection I would have my default gateway set on, but non connection to outside.......
