That's because you're telling ipfw to take EVERY tcp packet and cram
in into that transparent proxy, which obviously isn't what you want.
More likely you want something like
fwd 127.0.0.1,8080 tcp from any to any 80
or something. I've never used transparent proxy, but I can tell you what
ipfw does[1].
