Ubuntu, specify interface for a single destination ip
Solution 1:
This is a simple scenario. You need to have two things:
- Default gateway via
eth0. Next hop will be192.168.0.Y. - Static route for single host
8.8.8.8viawlan0. Next hop will be192.168.1.Y.
No need to add any rule using iptables.
You can add the default route and static route using these two commands respectively:
ip route add default via 192.168.0.Y
ip route add 8.8.8.8/32 via 192.168.1.Y
