in order for this to work you need to change a couple of things...
rc.conf:
ifconfig_dec0="dchp"
rc.dhclient: (if you are on road runner cable you may need to do this...)
interface "dec0" {
send host-name "bubba";
send dhcp-client-identifier 00:d0:b7:e6:fc:15; # this is your MAC
address
request subnet-mask, broadcast-address, time-offset, routers,
domain-name, domain-name-servers, host-name;
require subnet-mask, domain-name-servers;
}
rc.natd:
interface dec0
dynamic
use_sockets
same_ports
log yes
rc.firewall:
CHANGE ALL ${oip} based rules to use ${oif} instead.
