Hello!
Maybe my network topology is a bit strange, but I think I have no better/other posibility to accomplish my needs.
I have 3 Networks where my TMG is between as Proxy:
- a internal production network
- a testing network
- a VPN network
The TMG can connect through the internal network to the internet. Requests from internet are forwarded on a specific port to TMG.
The TMG should forward those requests to an OpenVPN-Server which is in the VPN and testing network. The VPN-Server listens on an IP-Adress in the testing network and TMG is forwarding to this.
However the TMG is recognizing every request from external as outbound and so my publishing rule isn't working, as publishing rules are only allowed for inbound.
My network relationships are:
Internal <- NAT -> External
VPN <- NAT -> External
Test <- NAT -> External
Internal <- Route -> Test
Test <- Route -> VPN
Can somebody tell me how/why TMG sees inbound traffic as outbound? Is this because external traffic comes through internal NIC?
Hope my explanation is good enough and I have provided enough information.
Thank you very much for any help!
Kind regards
Juergen
