Easy.  Or not...  You will need some information.
First, the default gateway for your LAN at school.  It should be on all of 
your friends computers.
Second, all of the static routes for your school up to the internet.  This 
could be tougher, but it may not be needed.  You may only need some subnets, 
but if you want to get to the internal servers, you will need to know where 
they are.
Last, IP addresses.  Either from the school LAN, or you can lay them on top 
of the school network as long as they don't conflict anywhere.  Either way, 
you will be unable to use DHCP.

Now, all of your friends must have a static IP with a default gateway of 
your m0n0wall box.  Your LAN (or OPT) must have a static IP in that subnet. 
You must also have static routes to the schools default gateway.  You may 
also need to use the schools DNS servers to resolve internal school systems.
