Ok, so the scenario is this:
I have a G5 Quad (running Leopard) with no wireless card. The G5 is connected by Ethernet to a Mac Mini (running Lion), which is picking up my AirPort Extreme network over WiFi. The Mac Mini shares its internet connection over Ethernet to the G5, enabling it to connect to the internet perfectly. I can also screen share or SSH into the G5 from the Mac-Mini without any problems.
Now comes the trouble:
I have a MacBook Pro (running Lion) which also connects to the same WiFi network as the Mac Mini. I can see (and connect to) the Mac Mini from the MacBook Pro without trouble, but I cannot see or connect to the G5 from the MacBook Pro.
How can I configure this so that I can SSH or screen share the G5 from my MacBook Pro?
