We have the following configuration: FreeBSD router with 2 network cards.
- first card has a real IP and connected to internet (lets say
220.127.116.11). There is a ipfw firewall which control traffic to this card.
- second card has another real IP (lets say 18.104.22.168) and connected to
Quintum VoIP box.
VoIP box has also its own real IP (lets say 22.214.171.124).
How should firewall be configured for card #2 for allowing VoIP traffic?
What ports should be open for normal VoIP work?
