Firewall?.... (usb WAN port?)

[Atari]

I've not even used the internet with the phone yet....

but I'm really used to having a hardware firewall.

Anyone know of any hardware firewalls with a USB wan port that would support these phones as modems?


I suppose a good stand-by would be a mini-ITX machine running linux & some hackery to turn that into a router/firewall box. But that would probably cost $200+++.

Anyone here doing anything like this already?
