I assume the error is in network gateway unit at 00:00:0c:15:e7:0d Yeah, this gateway seems to be configured to perform as ARP proxy, that is it sends an ARP packet with its own MAC address for every host that it thinks is not on local network (then it tries to deliver it according to its own routing rules, but in this situation it will hardly success :-)). Just disable ARP proxy on your router, or make it recognize your net as local, or move it to another ethernet segment, if you can't do either. > One network guru here is explaining the gateway unit is sometimes > answering too fast to the caller or something, faster than the FreeBSD > node. As I see from the ethernet address of your router, it's Cisco. I had similar problem some time ago, there was a misconfigured Cisco in our LAN, which we had no authorization to configure. And as I've seen, hosts under FreeBSD & Novell usually respond to ARP requests slower, than Cisco, and hosts under OS/2 and Win'95 used to respond faster. Of course, it could be due to hardware differences or host position in ethernet segment. -- Sincerely yours /&rew *** Andrew V.
