      Hi!

      I'm new to pfsense & just recently installed Snort & Squid package for company needs. Squid is working fine & configured whitelist. But for Snort I'm receiving unusual ping message from the ISP to LAN Gateways.

      Thank you very much.

        You have firewall rules that allow your ISP to ping your internal interfaces? Seems unusual. Or your ISP is somehow able to determine your internal interface IP and it trying to ping it?
