If your ISP is already routing these numbers to your main IP, then it 
should be easy.

I believe all you need to do is set gateway_enable="YES" in rc.conf (and 
reboot -- I don't know the manual way to accomplish that).  I think 
your box will automatically figure out which IP numbers are on which 
interface, and forward appropriately.  If not, you will need to set up 
a static route to tell it which interface the 209.../29 subnet is on, 
since it won't use the default gateway to the Internet.  Manually, you 
use the route(8) command to do this.  I think you can automate it with 
the static_routes="" entry in rc.conf, but I don't know the syntax.

You shouldn't need to run a real router daemon for this simple 
situation, so you don't need to mess with router_enable in rc.conf.

Now that I've typed all this, it occurs to me that the better answer is 
for you to read the appropriate section of the FreeBSD Handbook:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-routing.html
