Sounds like you want an ipfw "fwd" rule.

ipfw add 100 fwd 1.2.3.4 tcp from 10.0.0.0/8 to any 80

Then you set your web server up on 1.2.3.4 to catch the packets.  Only
connections from the 10.* subnet get redirected.  The fwd rule was
designed to work with Squid to create a transparent proxy cache, but
should do what you want.
