yamahaルーター コマンド・設定例

dhcp設定

• サーバー側

dhcp service server #ルーターをdhcpのサーバーとして機能させる
dhcp server rfc2131 compliant on #リソース情報を持たないDHCPクライアント
dhcp scope 1 192.168.1.2-192.168.1.191/24

• クライアント側

ip lan2 address dhcp

natの設定（静的NAT）

ip lan2 nat descriptor 1000
nat descriptor type 1000 masquerade★natの変換方式を定義
nat descriptor address outer 1000 primary★NATの外側アドレスを定義
nat descriptor masquerade static 1000 1 192.168.1.1 udp 500
nat descriptor masquerade static 1000 2 192.168.1.1 esp
nat descriptor masquerade static 1000 3 192.168.1.1 udp 4500

#natの設定（動的NAT）

ip lan2 nat descriptor 1001
nat descriptor type 1001 masquerade
nat descriptor address outer 1001 222.222.222.1

の問題がある場合は

• PC(Windows)をipconfig /renew,
• Wi-fi or イーサネットケーブルのどちらかだけの接続状態にする

静的経路情報設定

ip route network gateway gateway1 [parameter] [gateway gateway2 [parameter]...]

hide : 出力インタフェースが LAN インタフェース、または WAN インタフェース、PP インタフェース、TUNNEL インタフェースの場合のみ有効なオプションで、相手先が接続されている場合だけ経路が有効になることを意味する
