|You should be using switches not routers in this situation.|
Given you have the equipment, this is what you have to do;
connect a pc to the lan port of the dlink router
logon to the router
set its ip address to 192.168.1.2 for dlink1
set its ip address to 192.168.1.3 for dlink2
disable the dhcp server
save the config and logout.
connect a crossover cable from the westel lan port to the dlink lan port.
you do not use the wan port on the dlinks.
walla you now have glorified wireless switches.
dhcp ip will flow thru them from the westel to any connected device
all will have internet access and be on the same subnet.
end of story.
Answers are only as good as the information you provide.
