Hi,
I have a RB2011UiAS-IN which has the WAN port on eth1 with static IP .
The rest of the ports are bridged with 192.168.1.1/24 .
I have another router ( TP-Link ) in WISP mode conected through WIFI to another ISP and has the internal network ( 192.168.2.1/24 ) connected through wired connection to the bridge described above ( dhcp disabled ) .
In case the primary ISP fails how do I have to modify the default route to connect to the other network ( 192.168.2.1 ) through bridge to share the internet?
Already tried to change in default route from ISP’s GW to 192.168.2.1 and the ping to 8.8.8.8 from the router works but inside the bridge ( 192.168.1.0/24 ) the internet doesn’t work.
Hello
Can’t do that. Change the tplinks ip to 192.168.1.2/24 and disable dhcp on it.
Then plug it to the 2011. That way both routers are on the same lan _ and broadcast domain).
On the 2011, add a second default route with the proper gateway (192.168.1.2) and a distance value of 5.
Should you loose the ability to ping the 2011s gateway, your second default route will activate.
But that’s not the end of it because if you can ping the 1st isp’s gateway but go no further (isp internal failure), then your failover won’t work. You’ll have to do an extra step… But being away from my computer, I can’t remember what its called… Argh…

Well , it looks like it won’t work.
The TP-Link connects to a wireless network that has the same network ( 192.168.1.0/24 ) an receives 192.168.1.3
For his internal network it forces the change to 192.168.2.0/24 so I can’t change the network back to 192.168.1.0/24 to be in the same domain.
I can’t modify that wireless network and I don’t want to change my internal network from 192.168.1.0/24 .
