Hello. I have a web server with Ubuntu Server 12.04 and ISPconfig 3.0 installed. I have a dedicated ip address(with pppoe connection) and untill now all my services are working fine: apache2, mysql, pureftpd, postfix. I have almost 50 websites hosted on this server. All is working fine but i want to change my ISP and my ip address also. What files should i have to modify so that all my websites hosted until now on my server to not be affected. Thanks in advance.
If all sites are set to * in the ipv4 field, then there are no changes needed in the sites module. if you use the ispconfig dns, then change the ip in the dns settings. Beside that, you might have to adjust the IP iin the network settings (file) on your server.
