I've been using FW-1 for about 6 months. Recently I began getting incoming src of 10.10.10.7 and .170. No new machines have been added to the network, and from all indications the traffic is coming from my external interface. I have sat on the router and watched for the private IP range to traverse through, with no luck (it is just to sporatic). For a non routable IP I am at a loss of how to trace it down. tracert is not helpfull at this point. Any suggestions other than just blocking this?
