Rule: ICMP PING speedera Sid: 1:480 False Positives: The "Keep-Alive" feature enabled by default in many VPN Tunnels can trigger a false positive for this rule. Keep-alives make sure that a VPN tunnel stays established at all times by continuously sending ICMP pings through the tunnel. The tunnel is re-established if necessary. Nortel Instant Internet VPN devices have been observed generating ICMP traffic that is mis-interpreted by Snort as Speedera pings. ------------------------------- This is my first attempt to contribute to the Snort Rules database.
