Anyone ever experience a Sonicwall WAN setting change from full duplex to half duplex (on its own) and causing connectivity issues?
This happened on our Sonicwall TZ400 last week and since then, it has been a nightmare. Our VPN connection from this device to one of our offices keeps going offline (even though the VPN green lights are displayed) and reboot does not fix it.
We had to replace it with another device.
Any idea of what might be causing this?
The other tech said there are IKE security association expiration in the logs between the two sites that disconnect. I don't know if this is playing a role in the VPN disconnecting between these two sites.
