I installed ISPconfig on my network, behind a router. And my router has forwarding port direct to the server I installed ISP. I can open ISP through http://192.168.0.100:81 but can not open it on http://www.xyz.com:81. The server is connected to out side, it show apache test page on http://www.xyz.com. Port 81 is open to out side. What could be the problem?
are you trying to reach www.xyz.com:81 from inside your lan?? if so try it from outside your lan. maybe it will work that way.
I just tried it from out side my network and got the samething. I think I am going to reinstall from fresh again.
I rechecked my router again, apparently port 81 did not open. I swear I opened it before. Thank a lot for reply though.. This is very good community.
