I'm not completely ignorant of networking, the local side is fine with routing between 3 separate networks, split-horizon dns, etc. But there is something strange (read: I don't understand) going on between the router and the modem. Here is a lease recorded by dhclient:

lease {
  interface "xl0";
  fixed-address 123.123.123.209;
  option subnet-mask 255.255.255.255;
  option routers 123.123.123.209;
  option domain-name-servers 212.159.6.9;
  option host-name "coppermine";
  option dhcp-lease-time 60;
  option dhcp-message-type 5;
  option dhcp-server-identifier 192.168.1.1;
  renew 2 2008/6/17 21:04:46;
  rebind 2 2008/6/17 21:05:08;
  expire 2 2008/6/17 21:05:16;
}

So, to manually set this up I added to /etc/rc.conf

defaultrouter="123.123.123.209"
ifconfig_xl0="inet 123.123.123.209 netmask 255.255.255.255"

and then issued:

/etc/rc.d/netif restart
/etc/rc.d/routing restart

And, I can't connect to any external host. So, what am I missing?
