As I said in my previous postings, just like SIP ALG, it is usually completely broken and if you can't disable it, you are quite often screwed. The Zyxels are pretty good  - isn't there a newer device in their portfolio that might suit? Netgear is also reasonable if you get the right model.

This is slightly off topic for this list but I'm sure you'll easily find
how to setup a PPPoE connection for your distro.
