ICQPhone behind Debian masquerade

[Martin Budar <martin@budar.cz>]

Hallo,

I'm looking for help. I've some problems with ICQPhone (ICQ2000b) behind 
ipmasq. I've tried to use ICQPhone to connect to the friends outside my 
local network but it doesn't work well. I forwarded incoming UDP packets 
(UDP port 6701, which is used by ICQPhone) to my local IP using ipmasqadm 
portfw but it looks like only the first one packet went through. Outside 
packets are OK, so my friend can hear me but I can't hear him.

Do anyone know how to set up ICQPhone behind masquerade firewall?

Thanks, Martin
