Hi, I've been playing with ethereal a little, and I noticed that some webservers do an ARP lookup on my machine's IP address. This box is located behind a firewall, it is MASQ-ed and has a private IP. How is it possible that a webserver can request the hardware address of my MASQ-ed machine? Is something wrong with the MASQing setup or am I overlooking something. Is it necessary from a local network point of view to have ARP enabled (I could disable it with ifconfig)? If so, is it possible to deny (at the firewall) ARP-lookup requests from untrusted servers? I feel that giving away this kind of data is like giving away a Pentium III's serial number. Am I wrong or am I just being paranoid.
