Hi,
configuration:2 tmg sp2 EE, configured internal NLB(multicast), nlb working, all services work as should
problem:
when user connect to one external site with IP1 that have authorization through another external IP2, requests comes from different external IPs of TMG nodes. one to IP1 comes from node1 second one (authorization) comes from external IP of node 2 and authorization failed because requests should be from one of the TMG nodes.
if replace connection settings of IE from auto detect( which connect to proxy through internal NLB on TMG) to directly node1 or node2 everything work, traffic flow from one node
so question why request comes from different nodes and how to fix it?
