[Snort-sigs] SID 480 - False Positive

Subject: [Snort-sigs] SID 480 - False Positive
Date: Tue, 19 Oct 2004 14:36:16 -0500
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.

to provide any additional information. 
Your feedback would be greatly appreciated to let me know this message made
it's way to the right place.
