Hello ALL.......!

I am trying to redirect the traffic on the tun0 interface to loopback and I request you to guide me.

I have a tun0 interface and a when a client with an IP of 192.168.254.2 (coming from tun0) wants to access the Internet I do

$ iptables -A POSTROUTING -s 192.168.254.2 -t nat -o wlan0 -j MASQUERADE

and the client successfully connects to the Internet over WIFI.


Now instead of wlan0 I want to redirect all traffic coming from tun0 to Loopback on which I am running a BIND DNS server and also a lighttpd Webserver. I tried with few rules but failed to do so. Can you guide me with the right rule.

regards,

Altaf

First of all.. STOP


You dont want to route your traffic to your loopback device, ever.


So please explain here a little more about what you are trying to accomplish. You mention you have BIND and lighthttpd running so is it just your goal to have DNS lookups go to your internal BIND server first before going to internet? Which would then have a DNS record your internal website running of lighthttpd making it accessible from the client web browser?

It sounds like this is the case, and you will want to make changes to your /etc/resolv.conf to point to your loopback/systems IP so dns lookups go to your local BIND server, you also need to make sure you have your "Forwarders" set up so that any dns requests that are not on your local BIND server get forwarded to your ISP nameservers. Then just make sure you have a zone file on your local BIND server for your site(s) running on lighthttpd and you're set.
