network utility.app: wrong interface names

[Cancelliere]

In network utility.app I have the following settings:

1. Airport (en1), IP 192.168.2.1, inactive
2. Firewire (fw0), IP 192.168.1.9, active, 144 Mbit/s
3. Ethernet (en0), no IP, inactive

Why Airport and Firewire are "swapped"? I have never connected to my LAN with Firewire cable (I do not even know how to do it) and I am connected with Airport (everything works fine). Another strange behaviour is that:

MacBookPro:~ christian$ ifconfig fw0
fw0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 4078
	lladdr e8:06:88:ff:fe:f2:a6:f0 
	media: autoselect <full-duplex>
	status: inactive
MacBookPro:~ christian$ ifconfig en0
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	ether c4:2c:03:0b:d5:f4 
	inet 192.168.2.1 netmask 0xffffff00 broadcast 192.168.2.255
	media: autoselect
	status: inactive
MacBookPro:~ christian$ ifconfig en1
en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	ether 58:b0:35:7b:9a:ae 
	inet6 fe80::5ab0:35ff:fe7b:9aae%en1 prefixlen 64 scopeid 0x4 
	inet 192.168.1.9 netmask 0xffffff00 broadcast 192.168.1.255
	media: <unknown subtype>
	status: active

With ifconfig if seems that Airport is en1 and Ethernet is en0... but who gave it that strange 192.168.2.X address? I have only one LAN which has a 192.168.1.X address.

Cheers
Christian

Firewire can be used for a direct connection between two Macs. It is NOT meant to be used to connect to an Ethernet/wireless network.

As for your other questions... I have no idea! Check your preferred connection order in Network (System Preferences), though.
