Latest Updates
VPN compatibility with iOS 10 and macOS Sierra
Posted by David Cross on 20 September 2016 07:02 PM

Today marks the release of Apple's latest desktop operating system, macOS Sierra. Sierra joins iOS 10, released last week, in removing support for the PPTP VPN protocol, as announced by Apple Support.

Cipafilter firmware versions 9.1.0 and earlier do not support any alternative protocols suitable for end-user VPN access. As such, Cipafilter's VPN functionality is currently NOT compatible with iOS 10 and macOS Sierra.

A forthcoming release of the Cipafilter 9.1 beta firmware will introduce support for L2TP over IPsec, which is suitable for use with all major operating systems, including iOS 10, macOS Sierra, and even Chrome OS. We do not currently have a release date for this feature, but our developers are working hard to get it out as soon as possible.

In the meantime, customers who rely on PPTP VPN are advised to make alternative arrangements or simply delay upgrading their Apple devices.

If you would like to learn more about becoming a beta customer, please let us know by reaching out to

Google Public DNS Issues
Posted by Dan Schuler on 18 March 2016 10:16 AM

Yesterday we identified that Google's Public DNS servers ( & encountered an issue where they began returning either slow or invalid DNS responses. For customers using Google as both their primary and secondary DNS, this may result in websites seeming slow or unresponsive. Our proactive support team has been working to help alleviate the issue on affected customers. If you believe you are experiencing this issue, we suggest changing one of the DNS entries on the Cipafilter to point to another public DNS server, such as those offered by your ISP.
