Hello,
I'd like to configure my two Forefront TMG 2010 Servers that are currently in a Standalone array so that the second server properly takes the load if the first server goes down. I'm trying to implement failover by using NLB on the external network, but the servers don't seem to be accepting requests on the NLB IP. I'm currently using Multicast mode for NLB. Here's a rough overview of my network topology:
Internet --- Modem --- Cisco 800 Router --- TMG VM1 & TMG VM2 --- Internal Network
Both TMG VMs have their own External IPs. I'm forwarding ports on the Router to the NLB IP of the TMG Array. If I try to ping the NLB IP from the Router I get nothing, but if I ping their individual IPs I can get a response. Am I doing this correctly?
Any insight on how I can get this working would be greatly appreciated.
Thanks!
