Can anyone recommend an ethernet(not PCI or USB) modem that doesn't
NAT, and which will work reliably with the Linksys router that I've
been given? I already have a combined modem/router but the Linksys,
with it's open sourced firmware, looks interesting. Incredibly, the
linksys modem, the ADSL2MUE, does not work reliably with 54GS and is
really a simple NAT router.

Thanks

I've been told that the D-Link DSL-300T is the best solution - I'll
find out as I have just bought one too for the same application. Seems
to have the right specs & there is a gudei on adslguide.org.uk on using
it with the WRT54G
