Which ports to enable for firewall?

I'm behind a firewall (which I maintain) and can't log into the Internet server lobby in CTP2. Are there any specific ports I should be opening up and forwarding to make this go?

It looks like you need to forward UDP ports 21100-21299. I'm not 100% certain that's all you need, but you do need at least that. We are the last game to use Activision's Activenet networking library. And while it's quite good and should really continue to be used, there's no one left here who really understands it. So if you open those ports up and it still doesn't work, say so and I'll dig into it deeper.

You might also go look at the CTP1 site and see if there's any info there, nothing you (as a firewall admin) would care about has changed.

Thanks. I will give that a try this evening and report my results here.

I got it working!

On egroups.com, I found this post from Dan Kegel (who apparently had a lot to do with the Activision networking code):

quote:

Looks like you may need to do

echo 1 > /proc/sys/net/ipv4/ip_masq_udp_dloose

on 2.2.15 systems to allow playing games through NAT. This was the default on earlier kernels, but is now off for security.

I did that, and forwarded port 21157 (only), and that seemed to do the trick. I'm not sure that I even needed to autofw the port; I should try it without and see what happens.
