Re: [FW-1] Hide NAT arp on Linux



You need to add a static route for the hide nat to point
to the Firewall?

I've never had to do that, and dont' with the other hide
nat's on this same box.. the only difference is that this
one goes out a different interface...

Anyone else have any thoughts?

first I suppose that you already defined a public arp entry for your
external address on the firewall's MAC address.

Furthermore Linux needs a static route for IPs with public arps. On my
firewall I did the following for hide-NAT addresses:
route add <external IP> gw 127.0.0.1

good luck
