I’m in the final stage of opening our LYNC server 2010 implementation to external access but have a couple of questions regarding reverse proxy:
1) The reverse proxy and edge server sit in the DMZ which is protected by a PIX firewall. Why do I need to run TMG 2010 on the reverse proxy server?
2) Can I get away with Natting the necessary IPs/Ports to the DMZ interface?
3) If the above are not possible, can someone point me to the necessary documentation on how to install TMG 2010 and get it operational for LYNC
