So the "IP Gateway" is a MacIP server? Does it know it's supposed to route to the ethernet interface?

Does it treat the localtalk network as new completely new subnet?

Sounds like a routing issue. How is the SMC router supposed to know to pass packets for the IP addresses on the localtalk network via the Quadra?

Try running "traceroute" on the G5 with IP address for

(a) the SMC router

( B) the Quadra
