Watch their tech support. Sometimes you get clueless trainees. The MAC
address is used only to authenticate your one dynamic IP. I have BS
ADSL, and with Linux box on internal network, and no problems of any
kind surfing, etc (and the MAC addresses are different). I don't know
windows enough to say why they might be different. Also, BS uses cache
servers for all http traffic. Maybe this is a factor (I doubt it).
Maybe I am wrong here, but when the internal network requests go out
thru the Linux masquerader, they are showing its IP and MAC. The
problem is elsewhere.

I believe this is already the case. Check it with 'tcpdump -e' on
eht0.
