Hello Everybody,
I am a beginner to Linux and SME. I have installed a SME Server V8 on a normal PC using 2 ethernet cards and 1 modem for connection to the internet. I am running the machine is "Server and Gateway" moder, however during installtion I changed in once to "Private Server and Gateway", however I switched back to "Server and Gateway".
No everything is set up and internally the machine is working fine as Web-Proxy, Emailserver, MySQL Server, Fileserver.
However the services which should be reached from outside (Webserver (Apache) and Emailserver (IMAPS)) are not reachable as all ports are closed. I can see this by making a port scan from an outside Website (dnstools.ch) to my current IP. To make a cross check I installed another SME Server on another machine and made a port scan (right after the out of the box installation, not having configured anything) and could see that the required ports (80, 143) are open.
So I conclude: during my configuration of the main machine I have done something which rendered these services unreachable against the internet.
Does anybody have an idea what to do here?
Do I need to supply any additional information?
Thanks in advance for any help!
regards
Stefan
