I setup dimdim using the CentOS , I have set a static ip of 10.35.1.33. I can connect from our 10.35.x.x network just fine but when i try to connect from our 10.100.x.x network it will not work. I cannot even ping it. But I can ping the windows machine the vmplayer is running on 10.35.1.27
I have the correct gateway & subnet in the CentOS image. I verified the firewall is disabled as well.
Here you can see the steps I had to take to get it to configure my IP address.
