Im trying to diagnose a problem with our TMG deployment whos topology is edge server, There are 4 networks/subnets
1 Internal TMG (NLB)
2 External TMG no NLB as its just used for NAT
3 EAP WiFi (NLB)
4 VPN (NLB)
The TMG servers are hosted on a clustered HyperV deployment and all tmg servers have 4 NIC's and ive taken care to match the MAC address to the network and ip they should have so there are no mistakes there.
There is internet and lan access setup already for the internal networks and I already have a network rule to route between networks 1 3 and 4 (source 1,3,4 destination 1,3,4 relationship route) and on the other side (the routers)
But after enabling NLB on networks 3 and 4 I can no longer ping from either the tmg or routers.
Attempting to ping the router for the EAP WiFi network gives
Pinging 10.0.2.1 with 32 bytes of data:
Reply from 10.0.2.3: Destination host unreachable.
where 10.0.2.1 is the access point TMG 1 10.0.2.2, TMG 2 10.0.2.3, TMG 3 10.0.2.4 are the ip address's on the HyperV switch for this network For each TMG server and the NLB IP is 10.0.2.5
Attempting to ping from the access point to any of the addresses above again fails to work even though the access point shows both the Status & Line Protocol being up.
Can anyone suggest what might be the problem ? Like I said the problem started right after I enabled NLB.
