Q

Is it possible to make a VoIP call through the firewall?

I've got a SparkLAN WX-6215M Wireless 11b SOHO AP Router. If I configure a DMZ on this router, how should I expect it to work? I am planning to put a VoIP system in the DMZ, so would it be possible to make a call through the firewall?
Yes, it should be possible to make a VoIP call through the firewall once you open all the relevant ports on the firewall. On the firewall, you can create three zones. Inside is most secure, outside is least and DMZ is in between. All the servers or resources you want to access from outside should be in this zone.
