we would like to enable an external connection to a SharePoint 2013 farm via our Juniper appliance. I do find information about configuring a Juniper SA device for SharePoint 2010, but nothing about SharePoint 2013. Now SP 2013 is very different - it depends on URLs and heavy use of AJAX. Does anybody have experience on how to use a Juniper appliance as a reverse proxy for accessing SharePoint 2013? (At the moment we are using web resource profiles).
Juniper doesn't support SP2013 on any of the current IVE release.
The workaround would be option Client access mechanism such as WSAM, NC and Pulse.
Refer the below Supported Platform guide for 8.0R1:
