SMTP TRAFFIC ON CISCO 800 series Router

More
14 years 1 month ago #35627 by neveroff
I need to point the SMTP traffic to my 192.168.1.201 mail server. I have put in a static nat that points from my static ip to the 192.168.1.201 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 41.73.37.254 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
