> What does your arp table look like (arp -a) before and after DHCP?

Before DHCP:

(nothing was printed to the screen)

After DHCP:

? (192.168.1.1) at 4c:e6:76:50:86:f6 on bridge0 expires in 1190  
seconds [bridge]
? (192.168.1.103) at 02:62:11:f0:35:00 on bridge0 permanent [bridge]

I can see that something is definitely not right.  Not sure how to fix  
/etc/rc.conf so that it will be setup correctly, though.  Thank you  
for the help!
