ENDIAN Firewall - Wifi Problem

Hi all,

I have Endian 2.5 and i would like to configure in Gateway mode for for wireless users. In the server I have two network cards, one for the green Zone , whic have defined another gateway, and one for the blue Zone. From grren zone all works fine but I can't access Internet from wifi clients. I'm lost because if I do an NSlookup from a client in the blue zone Endian firewall resolves name but I surf the web. I tried from several notebook. The firewall rules are OK and I don't see any blocked packets.

Any help will be apreciated.

Thanks
