Servers Not Showing

[FalconZ1]

I recently moved into an apartment on a college campus and am having trouble getting Altitude to work.

I got our tech support staff at the college to open up the following ports. I can now login, but I still cannot see the Altitude Servers. I see one random server and the other 140 or so are all unresponsive.
Allow: UDP 27272 (Altitude game)
Allow: TCP 31373 (Altitude SSL login)
Allow: UDP 31383 (Altitude Update and some other things)
Allow: UDP 27276 (Altitude servers)

I manually set the SSL port to 31373 (though it seemed to work either way).
I have also played with the config file (upnp:false, etc. etc.) based on other users posts and your suggestions Lamster, but without success. I submitted a bug report this weekend if that helps.

I've been playing this game for years, I'd hate to lose it!

Thanks in advance,

Sounds like they're throttling UDP traffic (which might make the game unplayable even if you manage to join a server). This is a favorite tactic at some universities to protect the network from file sharing traffic (torrents typically utilize UDP packets). You can try editing ~Altitude/config/options.xml and changing
maxServerInfoRequestsPerSecond="40"
to a lower value, like 10 or even 1
maxServerInfoRequestsPerSecond="1"
and see if that helps.

you need to get the tech people to unblock the ports that the individual servers are using

I'll check with them regarding UDP throttling. I tried lowing maxServerInfoRequestsPerSecond to 2 with the same results, and have tried low values before although not that low (using a value of 1 doesn't seem to work by the way).

Are there other ports besides UDP 27276 that need to be opened to see the servers? That was my initial thought. Shouldn't I expect to at least see some servers with UDP 27276 open? What range of ports is being used for the servers?

Thanks

[lamster]

Yes, there are many other ports used by servers. Server hosts typically have many processes on a single machine and will use whatever ports they find convenient to host each Altitude server instance. That said, there are several servers running on 27276. Sunshineduck may be correct -- if a restrictive two-way firewall is in place you may need your system administrator to unblock both your local port (UDP 27272) and the target server's IP/port. For reference, official 1, 2, and 3 are hosted at
IP: 75.102.27.114
Ports (UDP): 50001, 50002, 50003

Thanks for the details lamster (and Sunshineduck for the assistance). That sounds like it could be the culprit.

Is there any way to figure out a list of ports that I should request them to open? I'm sure I'll have to settle for a list of most active servers or just the official servers.

[FalconZ1]

Opening the 5000x ports worked, thanks! I can see the official servers at least now. 3 is better than nothing I guess. I do prefer them, as long as people are playing them. If anyone knows IP's / ports for any other servers that are frequently used, that would be great too, thanks.
