After updating BM 3.7 to:

TCP610ha
BM37fp4d
nw6sp5e

My users cannot get to any website (through the BM proxy on 8080) that requires a port, such as:

http://dl.ocean.edu:8900/webct/public/home.pl or http://mywebsite.org:2082/

They get the NBM Error:

Status : 504 Gateway Time-Out
Description : Unable to connect to origin Web server.
Note : If necessary, please contact your Systems Administrator for resolution.

Any first places to look? I don't have any rule setup to block all ports besides 80 or 443 - I'm trying to think of anything I might have done recently, but I'm pretty sure it wasn't until I installed the updates that it stopped working.
