skus vyhodit -i ppp0 a -o eth1 z toho pravidla, aka ja defaultna chain 
policy na forwarde?

povol to aj na forwarde explicitne.

tcpdump na fw ti povie ze odisiel paket na dport 6881 niekam von? dostal 
nejaku odpoved? ak ano pusti ethereal na winxp masine ( nahodis winpcap 
z http://winpcap.polito.it a nainstalis windowsovy ethereal ) a pozri co 
odosiela a kam a co to vobec je.
