これで 終わった事情では 有りませんが 取り敢えず ping 試験をします 最 低限 各々の 疎通が 計られている事を 確認します。これを 前提に 試験をする

ブラウザにて ”http://192.168.0.1”を 入力 そうして ”管理”を 選択 ”PING 試験”を 選択すると
これは 192.168.0.5 を 入力した例ですが そうして 送信を クリックすると

同様にして 192.168.2.1 に対して 試験をする。

adsl modem の場合 は IP address のみの 試験が 可能で有るので 一応 local network の 関連は 完了 してると 考えられます。さて この状態で はた して 外部から web の 提供が 出来ているかですが このままでは 不味いのが にゃんたろうにも 想像が 出来ます。
そうです ”ポートマッピング設定一覧” において
インターフェース プロトコル ポート番号
IP アドレス MAC アドレス
poa0 TCP 80 〜 80 192.168.0.8 指定しない
poa0 TCP 25 〜 25 192.168.0.8 指定しない
これを 変更せなば なんねいということです。
にゃんたろう 拝！
