Jim, What you may have done is you may have set your NIC card into promiscuous mode, which tells the NIC card to intercept all packets on that network, not just the ones meant for that particular machine. What you may have seen could have been a result of that. -- Jonathan --------------------------------------------------- Jonathan Slivko - 4EverMail.COM - www.4evermail.com Web Hosting - Web Desgin - UNIX Shell Accounts JSlivko@4evermail.com - Phone: (212) 663-1109 -----Original Message----- From: owner-freebsd-isp@FreeBSD.ORG [mailto:owner-freebsd-isp@FreeBSD.ORG] On Behalf Of Jim Weeks Sent: Saturday, October 20, 2001 9:53 PM To: freebsd-isp@freebsd.org Subject: arplookup failed: Would someone please check me on this. I know this has been discussed before and I want to make sure I understand correctly. I am receiving the following error, Oct 20 21:16:21 server /kernel: arplookup XXX.XXX.XXX.XXX failed: host is not on local network Indeed the server issuing the request is not on the same subnet. If I understand arp correctly, the kernel is not able to respond to a mac address not directly connected to the subnet of the responding machine. After looking at the results of "tcpdump -n -e -p arp", I see a lot of traffic from several subnets. Should I be seeing arp requests other than those initiated by my default gateway or other machines on the same subnet? Why would this machine be issuing request for interfaces connected to a different subnet, and if it should, why isn't it directing the requests to my default gateway? Am I correct in assuming that this is a routing problem and not something I can correct from my end?
