SecureNAT Stopped Working? - 16.Mar.2007 2:55:37 PM

I'm running an ISA 2000 box. It's been running for about 2 years now without issue. Tuesday the SecureNAT stopped working. If I run the Proxy or FW Client my stations run find but without it nothing will pass (except port 80). I'm stuck. I read an earlier post that someone changed there NIC and resolved the issue, but that didn't help here. If anyone could shed some lights on this. I've stripped everything out of the protocol rules with the exception of one which is now All, Allow, Any, Always. Getting normal web access if fine by trying to get through random ports just hangs.

Upon further review I believe that the SecureNAT is working, but I'm getting Abnormal Disconnects after the connection is established (sc-status 20001). I removed the Any...Allow All rule and setup a rule for port 55321 which is a Linksys router at another location. I connected fine. Knowing that the port worked I changed a File Maker's web access port to 55321 (again out side of the ISAs external port), it seemed to try to connect but then failed. My firewall log show a sc-status followed by a sc-status 20001. If I remove rule or deny the port my log shows a cs-13301 (Request denied by the firewall policy) which is correct. I also get the sc-status 20001 when trying to do RDP on the default port or custom ports that have been set and programs that have to run through the ISA. I guess what I need help on at this point is why am I getting the sc-status 20001 on some things and not others. I'm not sure if there's anyone really reading this tangent of rambling, but it's making me fell better typing it?
