Restrict local UDP ports in browser "advanded settings"

I have public IP in my computer which runs some UDP daemons (i.e. a
SIP server). I don't want to expose such a SIP server to all the world
so I set iptables to block incoming UDP traffic (unless it is in
response to UDP traffic send from my computer to the exact origin of
the incoming one).

The problem is that with WebRTC I must be able to listen in any local
UDP port, and thus I cannot set iptables.

So, should the browser include in "advanced settings" some kind of
"rtp-port-min" and "rtp-port-max"? IHMO assuming "always NAT" is not

Thanks a lot.
