My network setup allows:
- no outgoing UDP
- no incoming UDP
Kad won't work then. Extended search results from servers either.
- no incoming TCP
Which will result in a LowID...
- outgoing TCP possible
It looks like you'll be able to connect to an eDonkey server with a LowID, but not to Kad.
- webbrowser, irc, messenger, it's all working
Fairly normal, because in these cases you use TCP to connect to a server, which is correctly configured (not blocking incoming connections on its side, that is).
Amule doesn't work right now. It's connected to a server but a search won't bring any results.
Maybe you're connected to a fake server. I'd suggest you remove all servers from your list and get a fresh copy from
http://peerates.net/servers.php which only includes verified, good servers and then mark as priority servers those that return useful results. You may also want to change the port number aMule uses.
Are there any settings or anything I can try? Or won't Amule work under that conditions?
eDonkey should work, but I'd strongly suggest waterboarding your network admin until he... well, does his job?
