導入して4、5日たつのですが、ｾｷｭﾘﾃｨﾚﾍﾞﾙ中でFWのﾛｸﾞを見たところ、

"ファイアウォール","02:45:24","受信","ARP","0.0.0.0","N/A","0.0.0.0","N/A","Conflicted ARP"
"ファイアウォール","02:45:25","受信","ARP","0.0.0.0","N/A","0.0.0.0","N/A","Conflicted ARP"
"ファイアウォール","02:45:26","受信","ARP","0.0.0.0","N/A","0.0.0.0","N/A","Conflicted ARP"

こんなﾛｸﾞが残っていました。これってどういう意味なのでしょうか？
PC起動のたびに残ってるようなので、気になりまして…
