Quake3 behind a firewall?

[Dekard]

Here is an email I recieved from Kevin he has a question about running Quake3 behind a firewall.


I have tried and tried, but I have yet to run a stable quake3 server! You
are my last hope! The problem is that people are constantly dropped while
playing. I believe this is the fault of my firewall. I have currently one
port forwarded, and that is the default 27960. Are there other ports that I
must open in order to run the server? If that doesn't fix it, I'm buying a
new firewall =P

Thank you for your time!

-Kevin


I know I have seen this before wasn't the solution they need to open more ports on the firewall?

OK, I'm going to let you in on a few of my secret LAN laboratory discoveries, see if these routing tricks work for you. http://63.167.10.249/admincentral/ubb/smile.gif

In this case the computer you wan't to route to is on IP 192.168.0.1 with a mask of 255.255.255.0

create these routes
UDP (not TCP but sometimes it's best to route both)

27960 -> 192.168.0.0
27950 -> 192.168.0.0

tricks - use with caution!

27960 -> 0.0.0.0
27950 -> 0.0.0.0

27960 -> 127.0.0.0 (sometimes 127.0.0.1 or 2..)
27950 -> 127.0.0.0 (sometimes 127.0.0.1 or 2..)

One of the results of this is that ANY computer (in the 192.168.0.1 - 192.168.0.253)on your LAN can pick up the 27960 port (not just the one at 192.168.0.1).

Give it a shot and report back your results. http://63.167.10.249/admincentral/ubb/biggrin.gif

More from Kevin-

I was wondering...is there a way to force Quake3 to use TCP instead of UDP?
I remember seeing some servers listed under multiplayer as TCP, not UDP. If
there is a way to do this, my problems are solved! =D


Any ideas?

[Zxel]

Sad to say you can't, Quake3 uses TCP for querying and stuff but UDP or SPX/IPX for the positional data. If you are a networking guru you may be able to encapsulate the IPX/SPX and route it over TCP, but that is some serious networking stuff (heck, you may be able to do that with UDP too - but I don't think so since UDP is connectionless).

P.S. for a complete discussion on the subject check out this BB thread: http://www.quake3world.com/ubb/Forum5/HTML/001672.html http://63.167.10.249/admincentral/ubb/wink.gif
