pppoeからIPoEに切り替えた時のメモ(rtx1200)

2024年2月3日

excite光からexcite MEC光に切り替えた時のメモ

書類はいっぱい届いたけど接続の設定値に関する情報は皆無でした。

  • pp 1 を tunnel 99に変更
  • ipv4のdefault gateway はtunnel 99
  • ipv6のdefault gateway はlan 2
  • qosで利用していたNICの指定もpp 1 から lan 2 へ変更
  • lan 1 をLAN内のipv6のdhcpサーバーとする
  • tunnel select 99
    • tunnel endpoint address 2404:8e00::feed:100 がないとipv4のサイトへ通信が出来なくなります。

configの変更点です。

メーカーによってはルーター設定画面に「ゲートアドレス」や「AFTR名/アドレス」の項目がありますが、エキサイトでは指定しておりません。
「自動設定」のままご利用いただくか、入力不要です。
