VoIP Firewall: Difference between revisions

Add an example for a consumer router (e.g. ZyXEL). Needs 6 rules - or 12 if your RTP port range doesn't include 5060
(Mention that RTP uses 2 ports, and that you can halve the number of firewall rules needed)

=Example consumer router config=
The following example is for an AAISP-supplied ZyXEL router. Because the Custom Destination Port range covers port 5060 we get away with half the rules!
