To resolve this issue, please upgrade to Pulse Connect Secure 9.1R1 and above. Starting in 9.1R1 (for AWS and Azure instances only), Pulse Connect Secure has a configurable option to change the source IP address for all VPN tunneling traffic to the internal port.
- Login to admin web interface
- Navigate to System > Network > VPN Tunneling
- Enable Source NATTING
By default, Source NATTING is disabled.
