HavenĀ“t used IPFW for a long time but ill try to remember.
Do you have port 80 open in your firewall configuration too?
Code:
${fwcmd} add allow tcp from any to any 80 in setup via tun0
or manually
Code:
ipfw add allow tcp from any to any 80 in setup via tun0
Also allow "any?" traffic to pass trough your rl0.
I think thats the right way youre going, no need for natd.conf necessarily
natd.conf
Code:
use_sockets yes
same_ports yes
unregistered_only yes
dynamic
interface tun0
#redirects
redirect_port tcp 192.168.1.2:80 80
