I have followed the Debian 6 Cluster setup on two systems that have dual Nic's. Right now the eth0 nics are configured in the two systems and both are in the 192.168.1.x range. I have gone through and added the resellers and domains (using domain module) and need to map in our external IP's. Just wondering if there are any gotcha's I might see since I have added all the clients, domains and the websites are active but the IP's are set to * which should be ok at least initially. All of the sites are currenly live on another system but all our Global IP's are in use so I will be mapping them all over to a single IP and changing DNS on the fly as I get all the email migrated over.. About to do DNS, Mail Accounts and all the databases. This is for about 33 domains and a couple hundred email accounts. I know there might be some hickup's but as long as the system will accept the new IP for the two systems without issue then it should be ok.
