SD WAN performance SLA down even there is no packet loss and 7.4.6

[RolandBaumgaertner72]

Hello,

we had quite some issues with this FG60 7.4.6 and SD WAN. With the update to 7.4.6 we dont have anymore "conserve mode" issues and we can exclude this as a problem.

BUT we tried now 3 times with SLA performance and all 3 times it happened after 12, 24 or 36 hours that the interface got DOWN. This interface is our VPN interface and we never had issues, VPNs were always UP.

I found a known issue (1023878) which should have been resolved in 7.4.5 but having 7.4.6 I think we still have the issue.

Anyone having the same problem and comming up with a solution or an idea? I tried to disable the WAN2 but nothing, I cant get it up again, the link is down even after removing all WANs from the Performance SLA. I am sure that the WAN is woring just fine.

Thanks

Hi Roland

Does the affected interface have a secondary IP address?

No, it is normal fiber connection with NAT between, 192.168.0.1 <> 192.168.0.254
