IPSEC VPN intermittent issue

HI,

 

I have IPsec vpn tunnel between Palo alto to cisco asa, tunnel is UP however it disconnect intermittently. Is there any way to check reason behind disconnection in logs? I have applied path monitoring but it show only UP and down logs not exact cause.

 

Thanks

Hi @DhananjayBhakte ,

 

Yes, there are plenty of articles for debugging/troubleshooting/setting up SSL VPN.

 

Please search right here on the LIVEcommunity or head to the Palo Alto Knowledge Base.

 

Here's are a few as an example:

Hello,

While the Palo Alto will not drop a tunnel due to no traffic, an ASA will. So if not traffic is flowing across to the VPN to the ASA, the ASA might drop the tunnel.

 

The logs should tell you why the tunnel is dropping.
