I am having problems setting this up. this is what I am trying to do. I have Chillispot (hotpsot) running on dd-wrt. Everything is setup, but the client wants only 80 and 443 to go through through the hotspot. I found this tutorial for dd-wrt but that doesnt seem to work.
http://www.dd-wrt.com/wiki/index.php/Iptables#Allow_HTTP_traffic_only_to_specific_domain.28s.29
Initially I tried to place the options at the top but didnt work. then i flushed the iptables and set only these three. I can see the pkts number grow but for some reason I can browse.
root@DD-WRT:~# iptables -nvL FORWARD
Chain FORWARD (policy ACCEPT 3105 packets, 2442K bytes)
pkts bytes target prot opt in out source destination
1629 230K ACCEPT tcp -- * * 0.0.0.0/0 0.0.0.0/0 multiport dports 21,80,443

Heres some info from the router, chillispot is the tun0 interface.
