kerry, for the VE2/VE3 issue i have asked marnix to provede help since he has macs on his desk ...
solving network issues without knowing IP addresses (and the other settings like router and dns) for each port and the exact cabeling is not possible. a computer showing up in network does say nothing about the route and the protocol the packets are using.
i need something like this (what should work btw):
MacPro external 192.168.1.2, mask: 255.255.255.0, router 192.168.1.1, dns: a.b.c.d (we don't care about which dns is used) - cable connected to router
MacPro internal: 192.168.2.2, mask 255.255.255.0, router: none, dns: none - cable connected to G5 internal
G5 internal: 192.168.2.3, mask 255.255.255.0, router: none, dns: none - cable connected to MacPro internal
G5 external: cable not connected
in case your MacPro external is using DHCP leave it as it is, just make sure the internal ports don't use the same range as the external port(s) ...
an allowed classC range for internal network is 192.168.x y where 0 <= x <= 254 and needs to be the same on both *ends of the cable*, and 1 <= y <= 254 and needs to be different an both *ends of the cable*, subnet mask has always to be 255.255.255.0
