--W/nzBZO5zC0uMSeA Content-Type: text/plain; charset=koi8-r Content-Disposition: inline hi i have router on freebsd 5.4 (5 interfaces), and today found the following entries in arp table: [router] /home/atr# arp 10.5.6.15 ? (10.5.6.15) at 00:40:f4:8c:c2:71 on fxp2 permanent [ethernet] ? (10.5.6.15) at 44:44:44:44:44:44 on fxp2 permanent published [ethernet] is it a feature, or bug ? i just tried to add permanent entries in arp table using 'arp -S ' command several times.
