Webmail "publishing" on non-standart port Cisco router 2921

[ayta-ayna]

Hi all!

We are going to "publish"(I don't knowif this is correct word to use;)) our mail server on Cisco 2921. As far as I know it can be easily achieved with static NAT. But the thing is, we don't want to publish it on standart 443 port i.e. we want router to listen for https connections on other port than 443, and then redirect this connection to internal server with private ip.

Thank you.

Use

ip nat inside port static tcp {MAIL-SERVER_IP} 443 {OUTSIDE_IP} {PORT YOU WANT}

Ay user reaching your {OUTSIDE_IP} {PORT YOU WANT} will be redirected to your mailserver on port 443.
