I've installed Bamboo server on Windows 7 64-bit. When I attempt to download the remote agent JAR using Firefox (under the same machine as the server) from http://my-server/admin/agent/addRemoteAgent.action the download hangs at 99% done and never completes.

If I use wget to download from a Ubuntu machine the download hangs at the same point, then a couple of seconds later reports "Connection closed at byte 97052164. Retrying."

I have disabled all firewalls and anti-viruses. One final thing I noticed:

1. If I download the file using the server's public hostname (going over a pubic-facing router), the download hangs.
2. If I download using the server's internal IP, the download works.

Thing is, I don't experience this problem with any other application. I am fairly sure that Bamboo is doing something wrong, like violating the HTTP protocol, causing the router to block communication.

My router is a WRT45G v2 running Firmware DD-WRT v24-sp2 (02/09/10) std-nokaid. How do I debug this further?
