Hello all,

I am having weird issue with arp/mac address on local gateway machine

The following is from /var/log/messages

Jun  3 21:14:58 nile kernel: arp_rtrequest: bad gateway 193.19.XXX.1 (!AF_LINK)

when checking arp table :

chesfw1-e1-0 (193.19.XXX.1) at permanent

The IP is an alias on a local NIC, rather than a remote MAC.
when I try to delete it I get

21:16:41 [root at nile ~]# arp -d -a
delete: cannot locate 193.19.XXX.1

The machine initially boots up fine with the right mac address for the
IP but then it starts showing these errors.

the machine is running routed and pf and is filtering about 20Mbps

21:23:08 [root at nile ~]# netstat -rn|grep 193.19.XXX.1
193.19.XXX.1       193.19.XXX.1       UHLW        1        4    lo0 =>
193.19.XXX.1/32    link#1             UC          0        0    em0

FreeBSD 6.0-RELEASE-p5 FreeBSD 6.0-RELEASE-p5

ifconfig :

        inet6 fe80::211:43ff:fee7:bd77%em0 prefixlen 64 scopeid 0x1
        inet 193.19.XXX.1 netmask 0xffffffff broadcast 193.19.XXX.1
        inet netmask 0xffffff00 broadcast
        ether 00:11:43:e7:bd:77
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active

Any ideas or pointers ?
