Networking help again

DHCP is turned off in routers 2 & 3.

Router 1 is beside my computer. I need router 2 to be able to reach router 3.

You can turn on the DHCP on router 3 but assign it a different IP group/range.

Example:
Router1 group: 192.168.1.X
Router2 group: 192.168.2.X
Router3 group: 192.168.3.X

Also on router 3, simply assign the IP address of router 1 as it's gateway.

This would let any PCs connecting to router 3 to get a "local" IP (from router 3) yet still get internet from router 1.
