[TriLUG] vonage behind nat

[Joshua Gitlin]

I have two Vonage boxes, which brought up the question, which one do I 
forward the ports to? It turns out you don't have to forward the port 
at all, it just works.

However, I have a linux router and can't get QoS to work properly. I 
set the priority flags for the packets in iptables, but it still 
doesn't work. If I'm downloading a torrent, for example, the phone is 
unusable.

What I'd like to do is have the phone adaptors on a separate subnet 
(well, they already are...) and possibly on a separate ethernet nic, 
like eth2. (eth0 is my cable modem and eth1 is my local network). Then 
I'd like to guarantee bandwidth to eth2 over eth1... not just 
"preference" VoIP traffic, because preferencing isn't working...

is this possible? Or do I just have my QoS all screwed up?
