I am monitoring the firewall from the internal network and from a re3mote site over the VPN.

Over the VPN the ping time is fairly consistent and never drops the connection.

Locally their are intermittent spikes in lag time and brief periods of no connection.

Any Ideas of what to check or how to fix the firewall

Check the internal network.  Do you have other equipment between the monitoring system and the firewall?  Do you have a loop in the internal network?  A loop means you connected 2 or more ports from the same device to another device.  That would cause issues.

Internally, that should be a more stable connection than the VPN.

The switch I am monitoring is the only hardware between the monitoring station and the firewall. The switch does not show any problems.

No loop in the internal network. Checked that. I do see some latency spikes in the internal connection to the switch but only up to 15 msec.  The monitoring station goes through three switches to reach the firewall.

Found our Ethernet tap was forcing the switch port to half duplex now and again. Removed the tap and problem is solved
