I am trying to configure pfSense in vmware workstation 8 on Win 7 host. My internet connection is always-on static ip type so I am given range of IP addresses and gateway with DNS. But before I could access any website I need to do web-based authentication by putting in user credentials (user/pass) on the url given by ISP and I am ready to access any website. So, I can see a green lights on the pfSense homepage (webconfigurator) and I can also tracert DNS (as shown below) privided by ISP but it doesn't redirect to the ISP authentication page so I am not able to access any website. It shows "Unable to resolve the server's DNS address" in Chrome Browser. The redirect login url is https://loginbom.tataindicombroadband.in:8443/home". Is it to do with firewall settings?

This question came from our site for system and network administrators.

First guess, you didn't define DNS servers under System>General Setup.

It seems it was blocking the access to login web page as it was considering it to be "DNS Rebinding attack". When I disabled it in the System->Advanced configuration page, it worked. – om sai May 21 '13 at 5:40
