I have a Pi with AP and static ip address 192.168.1.2. Devices connecting to the pi will have IP addresses between the range 192.168.1.2 to 192.168.1.20. I want to redirect all incoming web requests to redirect to the ip address of PI using iptables.
I have tried:
iptables -t nat -A PRETROUTING -p tcp --dport -j DNAT --to-destination 192.168.1.2
iptables iptables-redirect

why not just assign a different IP subnet to the wlan interface? (and route that subnet to the rpi, of course)

ok. I will look into assigning a different IP subnet to the wlan interface. but how to route that subnet to the rpi? newbie to the linux here :(

depends on what you're using for a router. if it's the rpi itself, you don't need to do anything else. otherwise just add a static route on your router for that IP subnet to the rpi's address. btw, you havePRETROUTINGin your iptables command above...useful for fishing perhaps, but not routing :)

@cas Thanks for your reply. I am using rpi itself as the router. i added address=/#/192.168.1.2 in dnsmasq.conf for redirection and for most of the requests, it works except for facebook and youtube. I think that is because of SSL certificate. If that's the case, it shouldn't work for google.com too but it does. Any idea what could be done. ? and about iptables, is there any command which can meet my needs?
