diag sniffer packet any 'udp port 500' or diag sniffer packet any 'esp' would also be valid. 'IP proto 50' is not a valid filter Enterprise_Firewall_7.0_Study_Guide-Online.pdf p. 443 https://community.fortinet.com/t5/FortiGate/Troubleshooting-Tip-Using-the-FortiOS-built-in-packet-sniffer/ta-p/194222
