Well, the default firewall configuration on your wireless router would be not to
allow external addresses to access internal network services, though you can set
up port forwarding if you want the outside world to be able to reach (for
instance) apache on laptop1.

Thats the simplest way of doing it, though you'll then need a firewall on your
server. Thats basically how I have things set up here, with dyndns (ddclient) so
the server can at least keep the same hostname when its IP changes.
