Hello secur-susers :-)

I am trying to use SpeakFreely conferencing software from an internal
masquedare network connected thorught a SuSE 7.3 box with SuSEFirewall 2
doing routing, masquerading and fw rules...

I need to do a proxy for UDP 2074:2076 so packets get forwarded to the
internal client Following are the iptables rules I would use:

iptables -A PREROUTING -t nat -p udp -i ppp0 --dport 2074 -j DNAT --to
iptables -A PREROUTING -t nat -p udp -i ppp0 --dport 2075 -j DNAT --to
iptables -A PREROUTING -t nat -p udp -i ppp0 --dport 2076 -j DNAT --to
(where ppp0 is the external NIC for the masquerading)

I tried to load these rules manually either to place them inside the file
/etc/rc.config.d/firewall2-custom.rc.config but all packets get drop and
never reach my client... Where should I configure this proxy???
