after reading http://www.howtoforge.com/installin...tabase-cluster-on-debian-5.0-with-ispconfig-3 it looks like it is a server, slave setup, if server goes down does slave, serve web pages to public automatically. or would i need a setup in front of these like this http://www.howtoforge.com/high_availability_loadbalanced_apache_cluster and since this is setup for lan setups would i need a nat solution in front of everything. i currently run ispconfig 2 on two servers and had a issue and am looking for a new solution i believe i founf the answer at this thread http://www.howtoforge.com/forums/showthread.php?t=47874 so i get this right if i have webserver1 at ip xxx.xxx.xxx.xx1 webserver2 at ip xxx.xxx.xxx.xx2 and i use ispconfig 3 setup above and put * in website settings i will be accessing both servers at the same time,,,,, Correct ? making them redundant with failover ? and i should be able to set the mail servers to 10 on webserver1 and 20 on webserver 2. so the mail servers are not confused. let me know if i got this one right i am working on two new servers at present. and would like to bring them up to production. or would a different setup be better..? thanks to all your expertise i really enjoy these tutorials
