Hi Sean,
I can give you the manual method for ipv4.
For traffic to cross between the two interfaces forwarding must be
enabled. That is done in sysctl.conf
net.ipv4.ip_forward=1
Then the default route is assigned to the router interface:
ip route add default via <gateway_ip> dev <router_interface>
Very straight forward.

But how do I make it persistent ?
The forwarding setting is sysctl.conf is persistent.
Here is a link that shows how to add settings using nmcli. These
settings should be persistent (can't swear to it. I kill networkmanager
with extreme prejudice :)
