One for the experts here.
I have an office wireless LAN which uses Fortigate Access Points connected to a Fortigate 310B router... This equipment has been in place and functioning perfectly for months with Windows clients.
Recently, I had reason to try and conect an iMac to the system.
The iMac finds the SSID, connects correctly, pings, tracert etc work just fine but there is no Internet either on Safari or anything else...
telnetting also appears not to work.
I tested the iMac on another WLAN and it worked just fine, so it's not a faulty iMac.
I have a feeling that there's a setting somewhere on the Fortigate that is blocking the Internet traffic from being returned to the Mac..... can anyone help?
