Hy
I have a redhat-release-7.2-1, with kernel-2.4.7-10 and
iptables-1.2.3-1.
I want to assign a public IP 200.40.199.221 to my PCs for access to
internet,
and the interface outside is 200.40.199.220.
iptables -t nat -A POSTROUTING -s 10.220.5.13 -o eth1 -j SNAT
--to-source 200.40.199.221
The problems is the router outside, not kwon the mac to 200.40.199.221,
because my linux not reply the
MAC assigned to 200.40.199.221.
my linux have a MAC entry to IP 200.40.199.221 equql to MAC of interface
outside.
Help me please.!!

Either assign 200.40.199.221 to that external interface, or make
sure you have a route to that address (even a blackhole route will do)
and use proxy arp.
For each of these solutions search the web as to how to set it up.
