Please show us your entire netstat -rn output, as well as entire ifconfig -a 
output, and even possibly the relevant network config lines from 
/etc/rc.conf too. I'm wondering if you have no other interfaces configured 
so it is defaulting back to this. The 'S' flag usually shows up in manually 
configured interfaces for network cards, e.g. NICs with an ifconfig line to 
activate them in /etc/rc.conf. 

Perhaps you are missing or have something slightly misconfigured in 
/etc/rc.conf. Possibilities might include no defaultrouter, hostname, etc. 
Note that /etc/rc.conf should be used for overriding defaults. The defaults 
are in /etc/defaults/rc.conf and this file should be left alone. 

Note the following are already in /etc/defaults/rc.conf:

network_interfaces="auto"	# List of network interfaces (or "auto").
ifconfig_lo0="inet"	# default loopback device configuration.

Maybe you have a network_interfaces="<iface1> <iface1> [...] <iface lo0>" 
manually listing the interfaces in /etc/rc.conf which is overriding the 
default "auto". Just some guessing on my part to give you some ideas.
