IPSec logs with "error writing to socket: Permission denied"

[davorin]

Good day

I am trying to migrate away a site2site VPN connection from a Fritzbox to a SRX240H.

Adding the IPsec tunnel phase1/2 and restarting IPSec I see in the logs of my 19.1.2 box:

Code: [Select]

Mar 3 13:10:02 charon: 05[IKE] <con1|1> initiating Main Mode IKE_SA con1[1] to x.x.53.70

Any fw rule I missed here?

I just got the basic IPsec rule and the allow ESP rule towards WAN.

Hmm...also see this in the logs when restarting IPSec:

Code: [Select]

Is there some package missing?
