OA 4308 - Authentication Issues - Release (DHCP?)

Post by arpimentel » 18 Jun 2008 13:04


I'm not sure if you are experienced with Data networks (usually I only see Voice in this forum), but here it goes... :)

I'm in a client that has an Alcatel Wireless Solution - OA 4308 Release This client has authentication by captive portal (all users have/should authenticate by this method)

They state that there are three issues that happen frequently:

1 - The user gets the captive portal. Inserts the username and password (correctly). And then the internet access is blocked. It's like it is not authenticated.
2 - A user that was never in this network, arrives and gets authentication and access to the internet without apearing or authenticating in the captive portal.
3 - Sometimes users get an IP but can't ping the default gateway and can get access to the captive portal. I've found that there are two main reasons for this: i) the DHCP server is giving an IP that is already given to another user (sometimes a ghost user that is disconected but still in the system), then detects IP Spoofing ii) the server is trying to authenticate a wireless user by MAC, failing...

Thank you.

Check your firewall settings for denied times and traffic that is allowable. Also, check out the logs and see what if any errors are coming through. All of the issues I had with authenticating had to do with my firewall settings.
