Hi, I've a linux as router nat + firewall (POLICY DROP for INPUT OUTPUT and FORWARD) but, I've put next rules for p2p software on FORWARD chain [... snip ... ] iptables -F FORWARD iptables -P FORWARD DROP iptables -A FORWARD -p tcp --dport 80 -j ACCEPT iptables -A FORWARD -p tcp --dport 25 -j ACCEPT [... snip ... ] iptables -A FORWARD -m ipp2p --ipp2p -j ACCEPT iptables -A FORWARD -m ipp2p --ares -j ACCEPT [...] Then... emule, kaazaa , edonkey and so on works very good but ARES can't connect. I've - iptables 1.3.3 - kernel 2.4.28 - ipp2p 0.8.0rc3 BUT, if I change policy iptables -P FORWARD ACCEPT ARES works, can connect. I've tried to guess tcp/udp ports with tcpdump without suceess. I guess that ipp2p only can block p2p on a ACCEPT policy firewall I must open some tcp/udp port ? Can anybody helpme ? bests andres. _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
