Default External access to "Virtual... Ubuntu 8.04"


I have now a workable mailserver, after following the "Virtual Users And Domains With Postfix, Courier, MySQL...Ubuntu 8.04". It's made as VMWare Server Guest install. I will deal with another remaining issue as fetchmail/getmail later.

I can now access the mailserver anywhere in local LAN, to read/write using Thunderbird email client or surf to IP/squirrelmail. I want to be able to access the mailserver in a secure way from anywhere on the internet, and I have made a portforward to port 81 (since I had a webserver using port 80 on a another virtual VMWare guest). It's hard to test from inside LAN, but I test every day when going to/from work since I commute by train, supplied with a wireless internet access.
No luck so far. The only thing that I have change in the Apache setup is the port to 81. Then I have open up a portforward in my router/firewall (Freesco) to the mailserver. A netstat -tap result in:

netstat -tap

Is there anything I could test from outside local LAN to see what's wrong here?

I appreciate any comment on this.
