Re: [FW1] Static arp entries for NAT



the static arp entry is for the valid external address and is applied using
the external mac address of the firewall.

If the fake address is 172.16.0.1, the one you want to map it to is
200.150.36.98, and the external mac of the firewall is 00:38:c4:a9:80:d3,
then your arp entry is:

arp -s 200.150.36.98 00:38:c4:a9:80:d3 pub (solaris)

and your permanent route entry is:

route add 200.150.36.98 172.16.0.1 (if added to the firewall in a script
file)
