How to redirect request for any host to my hostname within a local network

  • 772

I have a local wireless network running. It is not connected to the internet and it has a webserver (lighttpd) running on 192.168.0.1

This webserver has a website running on it.

I want to know how can I redirect the user to "192.168.0.1" whenever he / she tries to access any other IP on this wireless network.

I have "dnsmasq" as my DNS Server.

To summarise:

"http://192.168.0.1" ==> Allowed to access

"http://193.168.0.1" ==> Makes no sense in this local wireless network, so want to redirect the user by default to "http://192.168.0.1"

Thanks, Mahendra.

  1. You can try to add this row into you dnsmasq.conf:

    address=/#/192.168.0.1

    From man page: ... with the additional facility that /#/ matches any domain. Thus --address=/#/1.2.3.4 will always return 1.2.3.4 for any query not answered from /etc/hosts or DHCP...

  2. You can use iptables to redirect 80 port to yours ip

    iptables -t nat -D PREROUTING -p tcp --dport 80 -j DNAT --to-destination 192.168.0.1

    Okay, I solved the problem. Posting the solution here back with hope that it helps somebody in the future...

    I solved this by modifying the lighttpd.conf file. I added the following inside my lighttpd.conf file:

    $HTTP["host"] !~ "mydesiredhostname\.com" {
        url.redirect = (
                                "" => "http://192.168.0.1/"
                        )
}

    I even had to add the following to my dnsmasq.conf file: (thanks to the answer below)

    address=/#/192.168.0.1

    Thank you everybody for your time. Cheers!
