私たちは今、これに数週間苦労しています。適切に確立されたPPPoEを持つCISCO 3825(15.1 IOS)(つまり、CLI内からネットにpingできる)。
私たちが抱えている問題は、クライアントが外界にpingできないことです。クライアントをルーターに直接接続していますが、ネットに接続できません。設定:

ppoeは完全に確立します。どちらのインターフェースもup / upですが、直接接続されたクライアントを使用してインターネットにpingすることはできません。DHCPなし、クライアントには静的IPアドレスがあります
私はこの質問に答えたことは確かですが、私が読んだことで何も起こしきれませんでした。
注意すべきことの1つは、f0 / 1に255.255.255.255のbcastがあることです。クライアントインターフェイスは192.168.2.255に設定されています。これは問題でしょうか?ダウンタイムを可能な限り最小限に抑える必要があるので、本当にありがとうございます。
簡単な
Interface IP-Address OK? Method Status Protocol
GigabitEthernet0/0 unassigned YES NVRAM up up
GigabitEthernet0/1 192.168.2.1 YES NVRAM up up
Dialer0 <public ip> YES IPCP up up
NVI0 unassigned YES unset administratively down down
Virtual-Access1 unassigned YES unset up up
Virtual-Access2 unassigned YES unset up up

いつものように、直接接続されたクライアントからではなく、CLI内でpingを実行できます。クライアントのDNSが8.8.8.8に設定されている場合、ルーターにpingを実行できます。dia0のゲートウェイルートの問題のように見えますか?

すべてが今完璧です!
前もって感謝します、
