To set a default gateway, you can issue the follwing command:

# route add default <gateway ip address>

To make sure it gets set on each reboot you define a default gateway in
your /etc/rc.conf file with a line like:

defaultrouter="<some ip address>"

If you want the machine to act as a router then you need to turn on
ip forwarding.  You can do this immediately by issuing the following
command:

# sysctl net.inet.ip.forwarding=1

... and then you can add the following line to /etc/rc.conf to make sure
that this sysctl is set on each reboot:

gateway_enable="YES"
