Hi. I've a firewall running Netfilter/iptables 1.2.3-2 on Linux 2.4.13. Does anyone know of any issues / incompatabilities with Webservers running IISv5 on multiple NT machines with "Window Load Balancing Software"? The web sites run off their own IP's (about 30 of them) and some sites/ip's route through the firewall while others don't. However if they take one of the two "clustered" machines down, then everything appears to work correctly. Iptables rules treat all these website ip's the same. I know this is sketchy .. I was just wondering, generally, if there are any gotcha's with this setup that anyones heard of. (I'm thinking maybe something with the connection tracking and the webservers doing redirection between each other??) I couldn't find any mention of this problem in the Netfilter list archives, so I'm hoping its just a misconfiguration on the NT's.
