Hello all,
I have problems running programs that need to receive multicast traffic 
from the network in a jailed environment.
For example, a program udpxy I wanted to use, says: 
"setup_mcast_listener: bind: Can't assign requested address".
This looks like jail restriction. Unfortunately, I have no access to the 
jail host but I know people who have it. They also don't know how to 
solve this problem so I can tell them the solution if you provide me 
with any :) - please, does somebody know how to lift this restriction?
Uname -a  inside jail says (if it helps):

If any other information is needed, just ask. Thanks in advance for all 
responses,

M. Kurpel
