if i forward all outgoing nat connections(connections from hosts within
my network going to another network) on dport 110 to port 8110, will i
still be able to run a pop3 server for connection directly to this
machine that aren't being natted?
if not can i modify the rule so that the if the destination is this
machine to not route it ... you can only use one -d !... option per rule
should i -d !127.0.0.1, -d !192.168.0.1, or -d 24.104.....?
