Hi I've installed ISPConfig3 on a Centos 5.4 box, but I can't access the control panel using http://xxx.xxx.xxx.xxx:8080 Apache is runing fine: I can access the default apache page using http://xxx.xxx.xxx.xxx I have tried changing the port to 5555 which is used by another server from the same provider (in case 8080 is blocked by the datacenter). I have also tested the ISP config3 installation by changing the main httpd.conf to use 8080 and IPSConfig to use port 80. I can then access the control panel but can't reach the default Apache page. Having run system-config-securitylevel-tui , I can confirm Selinux and firewall are disabled. So I've definitely got a port access problem. Are there any other settings within Linux/Centos that I should check? (That may prevent use of ports 8080 or 5555) Or can anyone recommend another port to try? Thanks!
