Internet connectivity issue with iMac on Fortigate 310B through Wireless
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?

Yep, the Mac gets a legitimate IP address, DNS is assigned as per the settings in the Fortigate.
Just in case, i set a static IP address and defined the DNS (using 8.8.8.8 as suggested)
no change, the Mac still can't display Internet pages.
Also, tried leaving the IP address on DHCP but manually setting the DNS, still didn't work.

Any other suggestions on this one?
I presume you do not have MAC address authentication turned on on the Fortinet?
ASKER
Nope, no MAC authentication at all..... Windows clients just connect to it and work.

accepting my own comment as the resolution wasn't actually related to the question I asked.
Try setting fixed DNS settings in the Mac's network prefs.
Try using
8.8.8.8
and
8.8.4.4
which are Google's public DNS servers.
