VPN connection between 2 Netgear SRX5308 seem to be intermittently dropping

[Sspe]

This location has a IP phone gateway that is connection via VPN to remote location using two ProSafe SRX5308.

Lately we have drop outs during calls to remote location, not here at source.

On both devices I see:

Have the latest Firmware 4.3.5-3

VPN - connection status

IPSEC SA IS EXPIRING 

Active Self Certificates - Expiry Time

Feb 11 04:02:05 2017 GMT

Self Certificate Requests status

Active Self Certificate Uploaded

I am new to VPN so needing instructed as to if any of these entries would be the cause.

Is the certificate actually expired? (I have no other connection issues to the remote site other than the phones).

Where do I start looking (googling) to fix the IPSEC

Thanks in advance, sorry for limited details

Nobody?

This is the only instance of this happening?

Hi Sspe,

Welcome t our community! 🙂

It seems that your VPN connection is expiring. May you be able to try increasing the SA-lifetime(sec) under VPN > IPSec VPN? Let us see if it will still expire.

Regards,

I will give this a go as soon as I am able to drop the link.

Thank you!

How do I test to know if my VPN stays connected?

@Sspe,

You may go to VPN > Connection Status > IPSec VPN Connection Status or you can manually test it by sending a ping request to the remote location.
