No internet connection from restored configuration

Hi,

I've just installed ASG ver. 8.311 on two 2 Dell Inspirons as High Availability (Hot Standby) and then restored a ASG ver. 7.511 backup configuration on to the two new boxes. Everything internally is working fine I can access ASG web interface and I can access my server but I have no internet connection, plug my v7 box back in and I have internet access. I can't figure out what the issue is. HELP?

Thanks
