Multibox server hangs after remote client connection

[Ocean]

As always stated in the beginners forum, I have a problem with my MultiBox installation.
The server hangs, after the remote client connects to it. If I start the server on the other system, everything works fine.

See: Multibox server hangs after remote client connection ('http://www.dual-boxing.com/forums/index.php?page=Thread&threadID=3964')

Where can I find the source code of MultiBox? Or can anybody send me the sources?
The I will try to debug it on my own. Maybe it's a problem with my system. I hope, running MultiBox in debug mode will help to figure out, what's going wrong.

Kind regards,

if you add clients to the hosts file in /system32/drivers/etc this will go away

Many thanks for you hint.

Adding the ip addresses to the host file doesn't solved the problem, but gives me the crucial hint to find the real problem.

Root cause was my BitDefender firewall. Allthough I use the same version on both of my systems, they behaved differently. After enabling ICMP requests (disable stealth mode in the BitDefender firewall) connections in both directions works.

Now I'm happily dual-boxing LOTRO on Maiar.
