I need to point the SMTP traffic to my mail server. I have put in a static nat that points from my static ip to the mail serve internally.

When I do a telnet to the static external IP on port 25 I can not hit my mail server.

I had to create a PPTP VPN to my ISP from the Mail server. I used this IP in my static nat as my public static IP. The mail server is behind my router.

One of the big problems is, is that my IOS version on my router doesn't support PPTP VPN protocol.

Any ideas will be great
