port triggering with iptables

["Chow Kin Lum" <kinlum.chow@xxxxxxxxxx>]

Hi,

I have searched for a long time on net.
Can't get any useful info regarding how to implement port triggering using
iptables (kernel 2.4.22)
Those available information is all about ip_autofw, portfw etc. instead of
iptables.

Hope can get some input from here.

Thanks.
Regards,
Chow
