We have Configured TMG as firewall and to route the complete traffic from External to Internal.
We are now observing external to internal route is working fine however now traffic originated from internal to external is also routing.
I would like to know if we enable routing from external to internal will it automatically route internal to external as well. If this is not anticipated behavior, what needs to be tested?
My understanding is that, with our configuration
- Internal to External should NAT
- External to internal will Route as we have network rule in Place
