Why the fsck are you using reserved IP address space? Are you serious
that your ISP actually gives that to you? If not, please change to at
least RFC1918 ranges if you can't get public space assigned.

There's a few more settings like defaultrouter and gateway_enable that
you might need. Look up what they do before using them though.

If your xDSL modem runs in bridge mode, anything sent out the connecting
ethernet interface _should_ be picked up by it and passed on ``to the
other side''. You still need proper IPs for your external interface and
you still need to give a gateway to assign the default route to. Also,
you will need a subnet (of which the IP for the external interface is
NOT a member) to assign to the internal network.

If you can't do that, you'll have to run your FreeBSD box in bridge mode
as well, or just collapse the network (and turn the box back into a
host, not a router).
