Looking at the code above again, there's an error.  The first line is 
not going to do anything (I think, rc.conf has surprised me before). 
It should have the interface name.  So either of these two lines should 
work:

ifconfig_re0="DHCP"
   or
ifconfig_re0="inet 192.168.15.2 netmask 255.255.255.0"

If both were in rc.conf, the second would overwrite the earlier one.

I generally use "SYNCDHCP" to be sure a lease is obtained before the rc 
scripts go on.
