Comtrend DSL modem use iptables in their code. I discovered this while
trying to understood why small-MTU FTP breaks when issuing the PORT command.

DSL and cable modems are extremely simple devices. I'm amazed they have

Linux. (the 2 popular brands around here -- westell and motorola -- run
vxworks.)
