smurf pinging router?

I have a SMC router. This is in my status page:

My private addresses are 10.10.10.xxx The 12.214.xxx.xxx is public on the internet.

My boxes are 3 Linspire (Debian Sarge) and 1 Windows 98.

I think the log shows a box on my lan trying to ping the router. Unless it's someone with a misconfigured machine pinging the internet side. But I don't know enough to say.

AVG, Spybot, and Adaware say the Win98 box is clean. Do I really have Smurf on my Win98 box?

No it's not. It's someone on the internet side spoofing the IP address trying to be considered a LAN machine to gain previleged access, that's why it uses a private IP address.

I don't think so!! No one can ping on the internet with a private IP. It's not possible. Forget it!

Great! Thanks for the help.

There are a couple of alternatives I can think of:

If you have RIP advertising on, you could perhaps attract pings from various misconfigured clients in your immediate ISP surroundings.

Another possibility: one ISP (telia/comhem) I subscribed to, had a local

10.x.x.x network for their DNS servers; similar problems occurred if you tried using the same net locally, inside your NAT.
