TCP/IP can be active on both interfaces simultaneously. If you change
the network interface order, all that changes is the default interface
which will be used for outgoing traffic (governed by the routing table).

If you have two active network interfaces, both connected to the same
LAN, then typically the first one (in the order they appear in the list
of network interfaces) will be used for all outgoing traffic. The
computer will have two IP addresses on the same LAN, and may see itself
in Bonjour sharing (for example) under its other IP address.

If they are connected to different LANs, the order of the interfaces
will determine which network is used for non-local traffic, unless you
have special rules in your routing table. For example, if the first LAN
is using 192.168.1.x and the second is using 10.x.x.x, then all traffic
to 10.x.x.x will go out the second interface, but all other traffic will
go out the first interface (192.168.1.x will be local, anything else
will go to the default gateway on the first interface).

David,

Maybe you can diagnose an Airport/Ethernet problem for my wife and I.

Setup is: Residential DSL comes into our house, to a several year old
Cayman DSL modem which has 4 Cat 5 Ethernet ports on the front (which I
believe function as an Ethernet router, whether or not the DSL is
active?).

Connected to two of these ports are an Airport Extreme modem and an old
but very solid hp 6M/6MP printer, which does not have a built-in
Ethernet card but is connected to the router through an equally old
Farallon "EtherPrint" adaptor.

Two MacBooks in the household (one running 10.4.11, the other 10.5) talk
to the Internet via the Airport LAN-- and we used to be able to print to
the hp printer through the same Airport connection, by activating
AppleTalk in the AppleTalk tab of the Airport connection in Network
Prefs.

Something happened that cut off this "print via Airport" capability.
Now we can still use the printer if we connect Ethernet cables from the
laptops to one or both of the 2 other ports on the Cayman, and activate
AppleTalk in the Direct Ethernet settings in Network Prefs (which turns
it off in the Airport settings). And, doing this leaves our Internet
connectivity via Airport unchanged.

But, we can't seem to get back to being able to both surf and print via
the Airport connection only. Any advice on what might have gotten
messed up in our configuration would be appreciated . . .
