Firewall..

I'm using a openSUSE13.1 (bottle) in a VM with 2 Nics(bridged) for running my e-mailserver. One to my internal LAN and one to I-net in the VM(as well in the 13.1 host). Work like a charm.

I have run web-mail to my VM (served me well, both internal and external) but decided to educate myself and start using imap testing Evolution, Kmail and Thunderbird as clients.

1, made e-mailserver listening on 0.0.0.0:143
2, made e-mailserver listening on 0.0.0.0:993

Using Yast2 Firewall module and added above on ext interface.

3, SMTP was already listening on port 25 (UDP)?
4, HTTPS was already listening (on port 443 TCP)? I thought.



Tested with http://mxtoolbox.com to verify open ports from I-net:

25 smtp- success
80 htttp -success
143 imap -success
443 https -no connection could be made because the target machine actively refused it
993 imaps not mentioned at all in the test

Oh it works fine using port:143 to connect from I-net but what about 993? Why is not port:443 open?

I have a lot to learn :).
