I have an issue with mac Sirerra and High Sierra clients disconnecting from dynamic vpn connected to an SRX 220H2.
Everything seems fine until between five and ten minutes after connecting when the connection fails with no error message. The only way to resume is to disconnect and reconnect. The SRX is two years old and the sw version is 12.1x46.
I have tried two Pulse client versions, 8.1 and 8.3.
Has anyone else seen this behaviour?
This has now been resolved with excellent support from Juniper.
After extensive testing it was decided that packets were still being sent and received from the client Mac and that the problem lies somewhere with MacOS. We have implemented port forwarding for use by these clients.
