You turn IP forwarding on:

  # sysctl -w net.inet.ip.forwarding=1
 
You can do this automatically at boot time by setting the following
line in /etc/rc.conf:

gateway_enable="YES"		# Set to YES if this host will be a gateway.

You tell the machine that X.233 is the Internet gateway.  Make sure
your net mask is set correctly: 255.255.255.248.
