Hi,
we are running a 2 node TMG EE array with two EMS servers. I have successfully upgraded the two EMS servers to TMG SP2. After drain/stopping and suspending one of the TMG array members I have installed TMG SP2 on it. After rebooting the NLB services cannot be started again. In the Event Log the following error messages (Event ID 21215) appear in the application log:
"An inconsistency in the Network Load Balancing (NLB) configuration may
result in inconsistent handling of traffic between the VPN Clients network
and the Internal network. When a network rule specifying a route relationship
is defined between two networks, NLB must be enabled (or disabled) on both
networks. To enable NLB for IPsec remote site networks, enable NLB on the
network containing the local tunnel endpoint. To enable NLB for VPN
site-to-site and VPN client networks, enable NLB on the selected access
networks. Alternatively, for the VPN Client network, you can designate a
router for routing traffic according to the static address pool."
We have enabled NLB only on the external Interfaces because from my point of view it is not necessary to enable it on the internal interface (as stated also in the event log message). Before those error messages did not appear.
Any ideas?
Best regards
Thomas
