Well, the device seems to be responding to SNMP just fine. I can walk it (from InterMapper), I can poll it and it works like expected. However, the status window says that packet loss is 13% for all devices beyond the firewall. I'm suspecting the firewall does something stupid, but I'm trying to understand how InterMapper determines that there is packets loss, so I know what to look for in the firewall.
So, in short, not exactly. I guess the actual question is "which packets need to get lost for the counter to increase?" -------------- Andrey Khomyakov | Senior Network Engineer | +1.617.879.5945 Confidentiality Note: This e-mail, and any attachment to it, is intended to be confidential and might be legally privileged.

Is that the information that you need? Regards, Janice Losgar Dartware, LLC On Apr 16, 2010, at 3:00 PM, [email protected] wrote: > When IM says "Packet Loss" which packets are lost?
