How I hooked up VOIPo

[ctaranto]

I don't have this setup either, but it is preferred by Voipo. It must be secure enough, otherwise you'd be hearing of more ATA's being attacked or hacked.

There were many things I didn't like about the RT being first. A few of them are:
1. The feeling I was insecure by ports not being "stealth"
2. Relying on the RT to handle all NAT. If it's NAT abilities aren't good (and it's hard to find info on this), then when using many bittorrent clients, I will see a performance hit.
3. The QoS setup in the RT is no where near as good as a WRT running Tomato.

I do see a problem as chpalmer pointed out in his post. Your WRT's gateway should be 172.20.0.1 not 0.0.0.0 It's possible when you had the RT's WAN hooked up to the WRT's LAN that the router assigned this gateway to the RT as well. I'm assuming of course that you had the RT automatically obtain its IP address from the WRT's IP pool when you tried it before. You might want to see if that was the problem. If this resolves the issue, then you would want to reserve or assign a static IP for the RT in the router.

Interesting that the Tomato firmware doesn't even offer a "gateway" for the Router IP (maybe it assumes the Router IP as the gateway?). I don't know the effect of this setting in dd-wrt in the current topology vs. hooking directly into the WAN. I also didn't try dd-wrt and hooking directly into the WAN.

Thanks,
