Hi Experts,
I configured two TMG server and one EMS in my network. Rules are working file and they are replicating properly. I tried to use NLB feature so that if one TMG server goes down other should start serving services but not getting success.
I have 3 NICs in each.
Server-A
NIC1-192.168.0.10 (LAN)
NIC2-192.168.0.11 (I wanted to use for NLB delicately but how to define Im struggling)
NIC3-122.X.X.X WAN
Server-B
NIC1-192.168.0.20 (LAN)
NIC2-192.168.0.12 (I wanted to use for NLB delicately but how to define Im struggling)
NIC3-122.X.X.Y WAN
Reserved IP-192.168.0.100 for NLB VIP
I created Array and joined both servers. They are working fine. Now I tried to create NLB. Simply logged to EMS and on Network option clicked NLB. Server asked for LAN/WAN. I selected LAN and assigned 192.168.0.100 as VIP. After simply clicking save button all was done.
Once I do this the My both server are not accessible and they are changed into RED marks in System tab in EMS.
Can you help me to get the complete requirement/process to configure NLB in TMG 2010 ent.

HI,
for general information about High Availablity in TMG please read:

You must also pay attention for the NLB mode (Unicast, Multicast, Multicast IGMP):

I recommend to remove the additional IP (.11 and .12) from the internal network card of the TMG Server and use the DIP (.10 and .20) for NLB.regards Marc Grote aka Jens Baier - www.it-training-grote.de - www.forefront-tmg.de - www.nt-faq.de
