Email Server through NAT

Stupid question: 2 connections. S1/0 to frame-relay to branches. S1/1 to ISP. S1/1 uses Nat with overload. If I have an email server within my internal network, how can I get it to send/receive messages with ISP through the NAT interface? Will I have to set up another outside address just for this

Re: Email Server through NAT

One options is if your NAT supports port forwarding. Any SMTP requests are forwarded to your internal e-mail server. Otherwise you will need another IP address. Keith Townsend MCSE, CNE, CCNA Townsend Consulting www.townsendconsulting.com ""Jon"" <[EMAIL PROTECTED]> wrote in message 985rti$ikl

Re: Email Server through NAT

if you have one additional ip address, it makes your life a lot easier, but try: ip nat inside source your.emailserver.ip.address 25 interface.s1/1.ip.address 25 however, i don't know if you'll break your dynamic NAT for the rest of the folks inside by using this command... Port 25 is SMTP. yo
