結合されたLANインターフェースからWAN

UbuntuサーバーのLAN側とWAN側の間でパケットをルーティングできません。私はいくつかの援助を探しています。私のサーバーには5つのイーサネットポートがあります。1つはオンボード（eth0、WANに使用）、4つはPCIカード（eth1-eth4、bond0として結合され、LANに使用）です。どんな助けでもありがたいです。前もって感謝します。

以下のコマンドでこれを動作させることができました。私はufwルールでは不十分だったと思います。

Sudo iptables -A FORWARD -i eth0 -o bond0 -j ACCEPT 
Sudo iptables -A FORWARD -i bond0 -o eth0 -j ACCEPT 
Sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
