I believe the protocol changed with the latest patch for Diablo. This
rule seemed to work fine the last time I tried connecting to battle.net (a
couple of months ago):
ipautofw -A -r udp 6112 6112 -c tcp 6112

This is probably due to incompatibilities with glibc. Try finding a
version that has been ported to glibc or use a precompiled binary.

Usually, yes, although some daemons may have been compiled with support
for /etc/hosts.{allow,deny}. That depends on the distribution you are
using (I don't know what RedHat does, since I run Debian).

tcpdump is your friend. You can use it to monitor incoming and outgoing
traffic on your interfaces to determine where the packages are getting
lost.

I don't think this is the problem. 11 is just the hex code for 17.

Hmm, can't think of anything elso, offhand.

Ouch!

No prob.
