Huh?  Since when does that happen?  None of the boxes I have running
behave like this.  Or am I opening the in some mysterious way?  For
example, I have

# ifconfig -a
ed0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 192.109.197.137 netmask 0xffffff00 broadcast 192.109.197.255
        ether 00:80:48:e6:a0:61 
lp0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500
tun0: flags=8010<POINTOPOINT,MULTICAST> mtu 1518
        inet 192.109.197.137 --> 192.109.197.211 netmask 0xffffff00 
tun1: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
tun2: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
tun3: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552
ppp0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
        inet 139.130.136.133 --> 139.130.136.129 netmask 0xffff0000 
ppp1: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
        inet 127.0.0.1 netmask 0xff000000 

I've never used tun1 to tun3.
