Apple’s latest OS X El Capitan gives you simpler, smarter ways to do the things you do most with your Mac but our Technical Director, Roger Garland, is advising all our clients to hold off updating until further testing and versions are released.
Roger fully tests all public beta versions of any new OS X that Apple releases, this is to ensure all our clients are running a proven working OS that will not cause any disruption. He has discovered El Capitan causes networking and VPN problems, further information can be found here in relation to the Forticlient:
Please note – this is an El Capitan issue, NOT a Forticlient issue.
Basically El Capitan breaks The Domain Name System (DNS) – DNS requests from the VPN connected client appear to come from the Local IP of the client (i.e. DHCP IP that your home WiFi router has given you) – where it should come from the IP assigned by the VPN Server. So the DNS server can’t reply to you, as it doesn’t know how to reach you.
This needs fixing before we recommend any of our clients upgrade and we will post further information as Apple release further beta versions.
