the CAT5 patch cable from a normal port on your Untangle router should be leading to the WAN port on your Linksys router, or by using a crossover cable from a normal port to a normal port.
make sure that the IP address of the Linksys router is statically set in the same subnet of the Untangle router, and make sure that the actual IP is not conflicting with the Untangle router. I would also turn off any special filters that the Linksys router has, including firewalls and rule sets. you can configure that later if need be.
