I have a weird problem with one of my TMG2010 servers. I have an array dedicated to web publishing rules and it's working fine with one server, but I am having an issue when adding a second server to the array.
Joining the array goes smoothly, no errors are generated in the alerts tab and all the VIPs and static routes I've created in the config get pushed to the server with no problems. However the server is rejecting all incoming traffic to it, as if it is not applying any of the rulebase to the traffic and it is hitting the default deny rule.
Why would one server in the array behave differently to another? All network card settings are the same, TMG patch levels the same (SP2 rollup2), OS is the same (2008R2).
