question: i'm trying segregate internet <--> lan nat traffic for different networks using separate nic's for the lan's and a common nic for the internet (internet nic listens for multiple ip's). i would like to keep all incoming/outgoing traffic separated so that lan-1 uses internet_ip-1 and lan-2 uses internet_ip-2 etc...
i've done nat like this previously: iptables -t nat -A POSTROUTING -o <internet nic> -j SNAT --to-source <internet ip> but i'm not sure how to completely separate everything by ip/lan while only having 1 nic for the internet? sorry if this is a dumb question for this list. the need for this was kinda dropped in my lap suddenly... thanks for any help. - joe
