GU:

There are TWO ways to approach this problem

1.) you can assign the Linksys WRT54G an IP adress in a different
range e.g. 192.168.2.1 it would then hand out DHCP IP addresses to
your LAN devices in that range.

2.) put the ZyXEL P600 modem/router in "Bridge" mode. What this does
is disable the "router" functions of the ZyXEL and make it act like a
"Dumb modem" with no NAT no firewall - just a modem. You can find a
discussion of someone in a simular situation here:

There is a third option: connect B to a LAN port of the wireless router
and disable its routing and DHCP server functions, leaving it working as
wireless access point. In this case, the ADSL modem/router would remain
the device that does the routing.

CU;

Glad you got it sorted our and thanks for letting us know how you got
it working.

In general when one of these DSL Modem/ router things is put in bridge
mode EVERYTHING else, like logon, DHCP, NAT and so forth is done by
the downstresm router.

Have Fun
