Hi all,
I have a box I installed OpenBSD 3.9 on. I'm trying to get this box to
function as our office firewall. Here's the catch - we have VOIP phones
that contact an external VOIP server outside of our firewall. I've been
doing some research and found out that VOIP phones don't do NAT very
well, and because of that you need to put them on their own static IPs.
I've tried the sip proxy route, and honestly it was entirely over my
head and I just couldn't understand how to get it to work.
You are really asking for alot of work to try and do this with
two NICs. Here's how we do it as a service provider: 1 vlan
for data, 1 vlan for voice stuff. One device/router with
essentially three interfaces: one that serves as a wan
connection and two ethernet interfaces, one
for each vlan. Firewall the data vlan however you want, and
give each phone the equivlanet of a static address.
