I think I am really dense or something because I cannot get this to work.
Having said that, here is my configuration for doing Direct instead of NAT
since it was suggested.
The VIP is an external IP that I can ping. The real web servers are on a
192.168.0.xxx subnet. The VIP machine has eth1 that is on the
192.168.0.xxx subnet and I can see the pulse getting to those servers.
What I cannot get is anything responding on 80. It's as if the firewall
isn't letting traffic in or nothing is listening on 80.
So, if possible, tell me what to look for and what to check. Thanks
