View Full Version : Why cannot ping

Oct 18, 2012, 12:44 PM
I set up a G4 Mac 10.5.8 with two ethernet connections. Both with Static addressing. I have internet sharing turned on, with en0 being shared with en1

en0 is,, Router
en1 is,, Router

a laptop using is tied to port en0
a mini using is tied to port en1

so the schematic looks like;

(laptop <--> ( en0 - G4 - en1 <--> ( mini)

from the laptop I can ping,
from the G4 I can ping,,,
from the mini I can ping,,,

but from the laptop I cannot ping or

Any suggestions as to why?
