have the reliance broadnet in 3 different location for work and home.
And successfully installed the Linksys WRTGL wireless router and a home grown linux based router.
In all cases the WAN (internet) connection is DHCP. On powerup the router acquires the external IP address and DNS information using DHCP. The lan side is using NAT where the subnet is 192.168.1.0. As long this is setup correctly all the computers on lan should theoretically be able to connect to internet.
Now there is just one more step to connect workstations to the internet. The reliance broadnet connection page. The first workstation wil see this page and has to login. Other workstations wont have to repeat this. It's pretty annoying as the connection times out in 15 minutes. The fucker who thought of this is pure idiot. We have a static ip and need to provide incoming access and the stupid network is timed out.
It is a non standard way of authenticating, no router in the world supports it. The standard ways are PPPoE, PPTP, LT2P, Radius etc. After some digging around I found that the login page is posting "username" and "password" to this url
http://www.reliancebroadband.co.in/user/refresh/home.
So to make a workaround I wrote a script that makes this submit with the reliance username and password. And run it as a cron job every 10 minutes on one of the servers. Now the session never times out and no one has to see the dumb login screen. Of course I use linux machines so it's very easy to do it. If someone is interested I can share the script.
Peace
