Ok, so I have a dedicated server with the static primary IP address 89.200.xx.xx, it's running 3 VM's in virtualbox (all Centos 6 as is the server) and I have 3 other IP's that I want to assign to the VM's (numbers omitted for obvious reasons):
So I setup a bridge connection on the Centos 6 host and configured it to listen on eth0 and I assigned it the IP address 33.xxx.xxx.155. I then started the guest OS and configured it's static IP address to be 33.xxx.xxx.155 (this is after pointing the VB config at the bridge). I then tried to run "ifup eth0" and it returned "Error, some other host already uses address 33.xxx.xxx.155". OK. So I went back to the host and removed the bridges IP address. I then restarted the bridge and the virtual machine and assigned eth0 on the guest the IP address 33.xxx.xxx.155. Sure enough eth0 came up with that IP address, great! Except I can't access it. I have HTTPD running on the server and port 80 is correctly allowed in the IPtables but I can't see the server. I can't even ping it.
Any help would be appreciated, this is my first bridge network configuration.
