Hi,
Thanks for your reply. Now i have done some configuration changes rather i have rectified my some silly mistakes. I am able to find the login page . As soon as i type any website address it redirects me to the desired authentication screen. But when i login it shows me the Internal Server Error page. I am getting these errors in my logs. Please have a look, and help me :-

And my machine is behind the firewall gateway. I want to configure NoCat gateway on my machine, and want to test it with other system making that machine's gateway of mine. I am giving my whole configuration file here :-

You must install Net::Netmask if your running both on the same machine.
You must define "LocalGateway" in your authserv nocat.conf file. The
local gateway should be the ip address that is running both your
gateway and authserv.
Also not that it matters because I'm sure your're running in passive
mode but "HomePage" should be defined as your public IP address or
your FQDN and not as localhost. This is feature is used only in open
mode and redirects your customer or end user to the website you list
here after the splash. It doesn't necessarily need to be the IP of
your gateway but it shouldn't be http://gatewayIP/cgi-bin/login. This
will force the user into a loop and not allow them to login or gain
access to the Internet.
