Do you think it could be due to the Netscreen 50 being an old firewall and only having 100mb port capability? It connects to a gigabit switch but obviously only operates up to 100mb. Port utilization on the switch is showing 50%+ whereas all other ports are below 1% utilisation. Do you think the issue could be resolved by using a more modern firewall that supports gigabit speeds? It could just be struggling to handle the volume of traffic.
