IPSEC Site-to-Site up but no traffic after 1 hour

MMASLOUH

Hi,

In last 2 weeks i made an IPSEC tunnel between two sites, SiteA(Headoffice) and SiteB (Branchoffice).

Everything works well until yesterday, the tunnel stop forwarding data after 1 hour from established.

so every time i have to restart to the tunnel to make thing works, after 1 hour the tunnel keep up but no traffic sends or received.

    Hi MMASLOUH,

    Is IPSec tunnel set between XG to XG or XG to another device?

    Is your phase -2 re key set to 3600 second ( 1 hour) if yes can you set it to 7200 second under IPsec policy and confirm the  "forwarding of data stops after 2 hour from establishment".

    If after changing the IPsec re-key to 2 hours your data forwarding stops after 2 hours with tunnel status up then in this case the IPsec re-keying creating a problem and you may need to log a case to check the issue with support for further investigation with strognswan service debug logs to conclude it further. ( As it may be related to NC-53173 which we have observed with one case however device debug logs can give some more information for matching up and to conclude the issue similar to existing issue or not).
