Currently I have a static route:
ip route 0.0.0.0 0.0.0.0 172.20.xx.xx
where 172.20.xx.xx is my firewall. I don't want the firewall to process internal traffic so im adding another route:
ip route 172.20.0.0 255.255.0.0 172.20.xx.1
where 172.20.xx.1 is my gateway.
I'm just double checking to make sure this is the right thing to do.
