ISPconfig3 not working

I have installed ispconfig 3 on ubuntu 9.04 server. from The Perfect Server - Ubuntu 9.04 [ISPConfig 3] everything is fine without any error.

the squirrelMail is opening on this link http://77.68.52.128/webmail

the ISPconfig is not opening on the link http://77.68.52.128:8080
i changed the port of ISPconfig to 82 also it is not opening

i checked the port in the firewall he is listening to the port 82

what should i do??? why it is not opening??

 

You need to open port 8080 and not 82

 

thanks damir for your reply, but the port 8080 is opened also. and the ispconfig is configured to the port 82 now

 

What is port 8081 being used for?

 

I would like to know, too.

apache2 is running on port 8081 and nmap tells me:
