Hi all,
    In ipf.rules at the section below it says to run 1st rule, then look for ip address, put it in commented out rule and delete 1st rule . How do I know what ip address is my isp's DHCP server address?  >

# Allow out access to my ISP's DHCP server for cable or DSL networks.
# This rule is not needed for 'user ppp' type connection to the 
# public Internet, so you can delete this whole group.
# Use the following rule and check log for IP address. 
# Then put IP address in commented out rule & delete first rule 
pass out log quick on dc0 proto udp from any to any port = 67 keep state
#pass out quick on dc0 proto udp from any to z.z.z.z port = 67 keep state
