Advice for client behind firewall

[alymanbuttler]

My client isn't able to send or receive work units, and I'm pretty sure it's due to a corporate firewall. I know because when I put the computer on a private wireless network everything worked fine. I am able to open the assignment server links with a browser, no problem; they work on both ports 80 and 8080.

Any advice on getting FAH to work from behind a firewall? I asked IT but they are unwilling to help--they don't even seem to understand what FAH is.

Here's the relevant log:

Presumably the computer involved belongs to your company, so first, be sure you have [written] permission to run FAH on a corporate computer. (We don't want you to get fired.)

The typical firewal software recognizes specific programs and enables them to make outgoing connections to the internet (e.g.- your browser) and has a blanket prohibition against any other program making the same connection. (i.e.- if some unknown spyware happened to invade a computer, they don't want it exporting data.) What you need to do is to find out how to get FAHClient on the list of approved browsers.

That may be as simple as configuring an exception in software on your computer. Sometimes it's also done by configuring the approved browsers to use a specific proxy rather than just expecting that the nearest router is configured to establish normal outgoing connections.

Once FAHClient is recognized as an approved browser, it should be able to establish the proper connections with the FAH servers.

Thanks so much! I teach at a high school & use FAH for educational purposes. It runs on a personal computer that uses the district network, all of which is OK with administration. I will look into this "approved browser" list but I'm not expecting any help from district IT.

Please provide the information mentioned in the signature of my previous post. Something is wrong with your configuration since your system is trying to download /G80/Core_21.fah and there's no such FAHCore.

What security software is running locally? (Maybe somebody here will know how to grant an exception to FAHClient ... if that happens to be the actual problem.)
