Hello Everyone,
I've a problem routing Internal and Perimeter traffic to Subnets through a router.
Our network Layout:
What I want to achieve:
- Use TMG as the default gateway for the Internal and Perimeter network.
- Route Internal, subnets and Perimeter.
- Accomplish this without using a static route in the clients machines.
What I've done so far:
- Added a third NIC and Network for Perimeter.
- Added a Route rule between Perimeter and Internal.
- Added an Access Rule to allow traffic between Perimeter and Internal.
- Added a Range address in the Internal network (172.16.0.0 ~ 172.16.255.255).
- Added a static route using the OS or/and TMG console (172.16.0.0 255.255.0.0 172.16.71.8).
TMG settings:
- IPv6 is disabled in all NIC's.
- Adapters binding orders is (Internal, Perimeter, External)
- Only one gateway is set, and it's in the External NIC.
- Only one DNS server is set, and it's in the Internal NIC.
What is working:
- TMG to ALL.
- Internal to subnets (ONLY ping works)
- Perimeter to Internal (172.16.71.0)
What is NOT working:
- Perimeter to subnets.
- Internal to subnets (other than PING)
what I don't understand is that I have another TMG (built for tests) machine
with the same settings (without TMG SP 1 & 2) that can route to
subnets.
Thanks for your help.
