Port Issues

Hello to all you

Ok Need help here, naturally I’m running a WHS 2011, and the system is of course using port 80 and port 443 (HHTP, HTTPS)

The thing is I’m running an email server (AXIGEN 8.0.3) as well on the WHS2011 currently I’m running the webmail on port 81 (Default setup), (Reason for port 81 is cos WHS2011 is using port 80)
Using port 81 is not my desired port as unsecure…

Current setup for webmail I www.testsite.co.uk:81 as I have to put the port number after the URL a lot of business I go to block this kind of address so if I could type www.testsite.co.uk and this then lands on port 443 without having to put this after the URL then I’ll be happy as this site won’t be blocked at the business I go to and it will be a secure log on..

www.testsite.co.uk << is not my website by the way LOL

But you guessed it As WHS2011 is using port 443 already, I can’t use this port for the Webmail is there away round it ?

Thanks in advance
