To add a static route via a specific interface: where re1 is my wan interface and destinationip is your remote IP . You can do an ‘ifconfig’ to see your network interfaces
route add -host destinationip -interface re1
To delete the host:
route delete -host destinationip -interface re1
To add a default route to allow all traffic: where 192.168.1.1 is the default gateway
route add -net 0.0.0.0/0 192.168.1.1
route add default 192.168.1.1
To show all routes via a specific interface:
route show re1
