Hi, we need to get access to an external Oracle DB using ODBC from our Internal Network. We have MS TMG 2010 with SP2. I created an OutBound protocol definition for TCP 1521 and add that protocol to the access rule used for our internal clients (firewall clients).
However, we cannot get communication from our internal apps that use the ODBC connection. For example SQL Developer. I tried the same connection configurations from a machine outside TMG and they worked, so I am sure the problem is on the TMG.
I logged the traffic in the TMG and I can see that there are no errors but a few seconds after starting the connection I see a message in the logs saying " A connection was abortively closed after one of the peers sent an RST packet. "
Any ideas would be much appreciated.
