I use two PA820s for ipsec vpn and used certificate-Based Authentication for IKE
The 820-A version is 8.1.6 and the 820-B version is 9.1.4.
820-A configuration ike gateway no problem。
820-B will report an error when configuring ike gateway ，
authentication cannot have more than one subconfiguration,
I attach a screenshot for reference.
Do anybody have any suggestions to solve this problem?
