Hello there, I have been using ipchains with 2.2 kernel and after reading about Netfilter and outstanding manual iptables tutorial by Oskar Andreasson I desire to move to 2.4 kernel with iptables. I have some question though. In ipchains I have been using ip_masq_radio, ip_masq_irc, ip_masq_ftp modules (to make real Audio, IRC and ftp services to work). I understand that in new iptables I will be using ip_conntrack_ftp, ip_nat_ftp and ip_conntrack_irc, ip_nat_irc modules respectively. What about real audio? Do modules ip_conntrack_raudio, ip_nat_radio exists ? If not, will not I be able to use real audio ? I have Real Server on my network and would like to be able to conect from LAN Windows clients to conect to another Real Servers on the Internet. I would really appreciate if somebody would shed some light on this topic. Where I can find more information about it ? Best regards. Slawomir Orlowski
