Pulse client use dynamic VPN and it is NOT supported on the SRX1500. NCP based client VPN is supported on SRX1500.
Pulse Client only works with the SRX300 series of firewalls and is IPSec only and Windows only.
NCP works across all SRX’s we currently have, offers both IPSec and SSL transport, works on Windows and Mac and some to be on iPhone and Android. It has a Management app that can assist with large rollout to client
