Hi there,
This issue has been driving me crazy for the last month, and I thought I had it solved but definitely don't.
I have TMG configured for the sole purpose of being a reverse proxy for SharePoint, SAP BusinessObjects, and some other services to follow.
Everything works great... usually....
I put this in place for a client, I had it all configured, and I could reach both sites without any issue from home as well as my office. However, the client I put it in place for was unable to reach it from home, from his office, or from his cell, or anywhere really. The site would time out for him. On the TMG server I would receive an error stating: A connection was abortively closed after one of the peers sent an RST packet.
I searched all over the internet for this, and found a million posts about this error, and none of them helped me. I decided to reconfigure everything on TMG. I reconfigured everything from scratch, and it worked for me from home, on my cell, and worked for my client from his cell and from home, so we thought we were good. However, I am now trying to access it from my office, and it times out, and I receive: A connection was abortively closed after one of the peers sent an RST packet on the TMG server.
I tried from both of our external connections here at the office and I can't get to it, and the TMG server gives this error. I can still reach it from my phone and from home.
This is all done on the same laptops, so clients are not the issue. I've done packet sniffing, and the traffic makes it to the TMG and then nothing. Just a TCP Reset. The only difference at all is where the traffic is coming from...
I need to make sure that no matter where you connect from, if you have internet access, you can reach these sites... I have no idea why TMG is dropping the packet or why the reset happens from certain IPs.
Does anyone have any possible information that might help me?
Thanks
