Hi all,

I have some issue regarding ipsec tunnel at Palo alto, IPSec tunnel is up and running well before. Suddenly, data traffic is not working without any changes. When i reinitiate tunnel at PA side, it is working fine. it happens frequently, i'm not sure about the cause, what would it be?.

Hope i got some helps. Thanks much.

BRs,

Does tunnel come up when initiated by peer side but traffic don't flow or tunnel does not come up at all?

Does peer side have only 1 ISP or multiple? Any network changes on peer side?

After reinitiate, tunnel is working fine well. Peer has one ISP and no changes at peer side. Thanks.

@SoeSoeMyat,

What type of device is the peer? What version of PAN-OS are you running on the PAN side of things and what is the overall uptime on the device?

Peer is fortigate, PAN OS is 9.xx latest patch. Overall uptime is so long, may be 1 year.
