General Questions

i dont know if this has already been answered but here it goes.

i have multiple IP's that m0n0walla uses. one of the ip is uses connect to a mail server (***.***.***.164) it accepts connections and forward them to the internal ip (.125) when the mail server send out mail how ever it ddoes so with the ip address that it is attached to

in other words when monowall uses pppOe it gets assigned a static ip. (.166) i connect it is sending mail from that ip address, and i want it to send from the ip address (.164) the one i have it acceptiiing connections for. Is this poss and if so would you please explain how i can have it doing that.

Thank you so much for your help

Off the top of my head, I think that you need to use 1:1 NAT.
