ipfw allowing browser only

[David Banning]

I am trying to filter out all traffic except browser traffic.
So I tried 

01000 allow tcp from any to 192.168.1.6 80
01100 allow udp from any to 192.168.1.6 80
01200 deny ip from any to 192.168.1.6
65535 allow ip from any to any

But this does not allow browser traffic.

I have my browser traffic redirected via ipnat - ipnat rules are;

rdr dc0 127.0.0.1/0 port 80 -> 192.168.1.1 port 8180 tcp

I don't know what comes first, the redirect or the firewall, so maybe
I should be allowing traffic to 8180?

My host is 192.168.1.1 and the win browser is at 192.168.1.6

Any help here would be appreciated.
