Server with Perfect setup, not functioning in Datacenter

[Hans]

I have setup my new server according Falko’s “Perfect setup” for Debian Sarge.
I have tested this server at home and everything was functioning fine!

After changing the network-settings like DNS-servers, IPadresses, subnetmask etc, I have brought the server to a Datacenter a problem appears.

I have connecion on ports 21 (FTP) & 22 (SSH) but…no connection through port 80 (http).
When I ping to the server there is no data loss.

What could be wrong?

Please try to help me.

Did you use ISPConfig? If yes, have you changed the IP adress in the ISPConfig web interface under management > server > settings and edited each web afterwards, selecting the correct IP and saved afterwards?

If this wont help, please post the output of:

netstat -tap

Till, everything is functioning fine now.
I made a little mistake in the networkconfiguration.

Thanks again for your quick reply.
