hi !

i have an ibook with Airport and a G4/400 and a D-Link Wifi Access Point, and a router to connect the G4 and the AP to internet.

while developping carrafix, i would like to test this configuration :

1)detach the eth. cable from the g4 (the one which was connected to the router)
2)connect the ibook to internet via AP without eth cable
3)attach the eth cable from the ibook to the G4 to test internet sharing...

but before activating internet sharing, i was badly surprised :

my ibook configuration (in Network pane in Syst pref) is defined in this order of priority :
1 : Ethernet cable
2 : Airport
(3 : RTC modem)


when i tryed to ping the router from the ibook, it didn't worked ! but the G4 ping worked
if i change the order to
1 : Airport
2 : Ethernet cable

it's ok, i can ping the router but the g4 is unreachable

but isn't this order just a matter of preferences, ie the preferred order to acces to internet ? i mean that if the first choice failed, the second is tried ??

i thought that the ibook would have tested the eth cable first, see there is no route to internet, then test the airport link, and keep it ! all this automagically

am i wrong ?


thanks to give me hints

When multihoming like this, you have to have each NIC in a different subnet, otherwise you have to do major mangling of the routing table so that the system knows which NIC to use for each IP address.

Are you using different subnets on the two NICs, or are they the same?
