アドレス変換、DHCPリレー、 アクセス制御の基本

Posted at

NAPTの手順

①変換後のグロアドは何を使うか & グロアドを入れとくプールの名前設定
  (config)#ip nat pool "プール名" start-ip end ip netmask "ネットマスク"
②変換前のプライベートアドレスの範囲を定義する
  (config)#ip access list 1 permit "プライベートアドレス" "ワイルドカードマスク"
   <注意1>プライベートアドレスはネットワークアドレスを指定。x.x.x.0のこと
   <注意2>ワイルドカードマスクは00000000|00000000|00000000|00001111 等と
   チェックしない箇所には0を立て、チェックしてほしいところには1を立てる。
③グロアド、プラアド双方を紐づけてあげる
  (config)#ip nat inside source list "アクセス制御番号 今回は1" pool "プール名" overload
