I have two Ubuntu PCs as routers.
This is how it is setup.
Milwaukee
Eth0 not connected - 172.18.0.1/16
Eth1 connected to Green Bay 172.17.0.2/16
Green Bay
Eth0 connected to my PC 172.16.0.1/16
Eth1 connected to Milwaukee 172.17.0.1/16
I wasn't able to ping 172.18.0.1 from Green Bay. Same thing when I ssh to Milwaukee and ping 172.16.0.1.
It says "Network unreachable"
Here's the config files.
