Symptoms:

When using Pulse on iOS, Android OS or Windows Mobile, or Pulse 5.0R2 and lower on MAC OS X,  attempts to create an IPsec tunnel to the SRX device via Dynamic VPN fail with the following message being generated:

Solution:

Use a supported client. 

The SRX Dynamic VPN feature supports the following client OS versions:
