asterisk users - Aug 2003 - Configuring iptables to allow sip and dynamically allocate rtp ports

Hi,

We have an asterisk box, with 2 nics, one with internal addressing, and the
other with a public address. The firewall (iptables) is configured for nat
routing. Now we want to allow this box to receive sip registrations from the
internet. Does anyone know if you can use iptables to allow the dynamic creation
of rtp ports?

Not sure about making the ports dynamic but I just opened up inbound UDP ports
10000-20000 as in rtp.conf (these can no doubt be changes to what ever you needs
require) which has been working well so far..
