You are correct, and that's all it probably means. Someone on your ISP side (and it could be the ISP itself) is using the 192.168 address space. Our ISP here uses the 172.16 private address space for a bunch of stuff, including all their internal mail relays.

One of my FreeBSD machines acts as a router, providing shared internet access via ipfw/natd to the local network. Recently I've been getting a lot of these in the logs: arp: 192.168.1.1 is on lo0 but got reply from (someEthernetAddress) on xl1 xl1 is my Internet-facing interface. The address 192.168.1.1 is configured on the internal interface, xl0 not xl1. The address mapping for 192.168.1.1 is a permanent entry in the ARP table. 1) After reading the arp(4) manpage am I to assume that someone on my ISP's side of things has something terribly mis-configured? 2) If the local host has a permanent entry for 192.168.1.1, why would it send out an arp request for an address it already knows (is this normal)? Just trying to make sure it's not something I screwed up... -Modulok- _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]" _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
