Hello, When executing arp (on host A below), it lists 36 address pairs for an interface (eth1). This doesn't make sense to me. The interface is NAT'ed though. There are only two NICs on my computer and only two computers in my domain: to isp | | eth1 +------------+ |host A | |(does NAT | |for host B) | +------------+ | eth0 | +-------+ |host B | +-------+ The list in arp includes google.com!
