I think your problem is HERE! xl0; you are using dummy IP between two real
IP interfaces, you can use dummy IP on the inside LAN machines but not on
the external interface to your router/gateway.
NATD will be helpful if you are using fake IP in your inside LAN otherwise
giveup on it. The other issue will be you can not have both interfaces xl0
and de0 in the same subnet and be able to route between them.
