Hi Mate. Thanks for your response. I don't think so , the wan is set up statically and supplied by a data centre. The connection will be coming from another firewall VLAN. When we plugged the older pfsense in with the same config no issues were occurring. Just trying to look through the logs using shell due to the fact they only show a certain time in the GUI. Thanks

This won't answer all your questions but, I did find this on reddit: https://www.reddit.com/r/PFSENSE/comments/8hbsze/xg7100_performance_with_suricata_at_1_gbps/
