    HI,

    create a Firewall policy rule which allows the RDP Protocol from INTERNAL To EXTERNAL for ALL USERS. The clients must be Secure NAT clients

    Hi,

    Thank you for the post.

    Secure NAT client means its default gateway should point to TMG server. What is TMG live logging tell when internal client RDP to external client?

    Hi,

    Thank you for the update.

    On TMG server, you should add internal subnet(subnet behind switch core) to the network definition for Internal. And then add a static route from the command line to point to switch core.
