Dear Experts,
I have some questions about publishing multiple services with TMG's ISP redundacny with load balancing:
We are using a single TMG 2010 server to protect our network and providing Internet connection to them. We manage our own domain providing the name service with the DNS server component installed on the TMG box and published it outside. We are using Exchange
for mail service, as well we publish web sites too and terminal services via RDP. There wasn't any problem till today, when we got an other, separate Internet connection via a new different ISP. When I set ISP Redundancy to Load Balance I faced to a problem.
The Internet connection works fine, but the partner SMTP's drop our letters, because they can not complete the reverse DNS check.
How can I set the TMG and/or the DNS to provide a correct mail publishing service? How should I set our DNS to provide access to our web sites and other services when one of the Internet connections brake down?
Thank you in advance!
Thomas
