We need to determine external IP of clients, that connect to our internal servers (Exchange - OWA+Mail) through TMG 2010 (AD authentication). We found these log entries in TMG log:
- time - external client IP
- time - virtual IP - internal server IP - account
But we unable to correlate these entries to get:
- external client IP - internal server IP - account
Is it possible? Or may be there are any other logs?
P.S. We use reverse proxy feature and can't enable Secure NAT.
