RE: [FW1] RE: NAT - Manual or Auto??



Well, didn't want to start a flame war on the topic. I agree that auto NAT
is the right choice in very small environments. But i can think of many
occasion where simple automatic static NAT rule are not sufficient, not even
for a SMTP-Server.

I'll retire from this thread now.
