What does this mean?

[bryan2010]

I was fooling around w/ RouterRooter, a little util that lets you see incoming/outgoing connections on a Linksys router. Well, I noticed an incoming connection from one of my ISP's DNS server on port 53 to my computer on port 2001(which is forwarded to my computer), which I have my FTP server on. What is does the mean??
Really curious...

I have no idea, but this RouterRooter sounds cool. Do you have a link?

Just a simple Google search'll do ya, Russ.

RouterRooter

My question is...will this work on a NetGear RT314? It looks like a simplified sniffer, so I suppose I could just stick with Sniffer Pro and tcpdump.

It means they are checking you out, Mr. Smart Ass with the funny port!

Realistically, someone probably port scanned you and found the FTP. They're on your ISP too and spoofing as the DNS server (or are spoofing it knowing about your ISP).
