Hi.
No attachment made it on here, so I can't comment *specifically* on your issue, but I'll make a wild guess.

We have a Netgear router here that has issues with the first hop - showing a lot of packet loss when more than one target is being traced to. The second hop is fine, though - which means it's just the way the router responds to ICMP TTL=0 packets. We talk about that issue here:
