DD-WRTルーターでOpenVPNを使用してインターネットとローカルDNSサーバーにアクセスできません

DD-WRTルーターにDnsmasqとOpenVPNサーバーをセットアップしようとしました。

私の目標は、openvpnを介してdd-wrt(v24-sp2(03/25/13)メガ)ルーターに接続することです。

  1. 私の地元のリソースを使用して、
  2. dnsmasqconfigに入力したDNS名を使用してそれらにアドレス指定します
  3. すべてのインターネットトラフィックを自宅にルーティングします。

OpenVPNサーバーとdnsmasqの設定をいくつか行いましたが、オプション1が機能しています。

しかし、私は仕事の選択肢を2と3にする方法がわかりません。誰かが私を助けることができますか?

クライアント構成(OpenVPN v2.3.4):

client
dev tun
proto udp
remote some.server.net 11193
redirect-gateway

cipher AES-128-CBC
auth MD5

ca ca.crt
cert client.crt
key client.key

nobind
comp-lzo
persist-key
persist-tun
verb 3
float

#resolv-retry infinite

OpenVPNサーバー構成(私はGUIモードを使用しました): OpenVPN server config

ルーターのファイアウォール構成コマンド:

iptables -I INPUT 1 -p udp --dport 11193 -j ACCEPT
iptables -I FORWARD 1 --source 192.168.144.128/25 -j ACCEPT
iptables -t nat -A POSTROUTING -s 192.168.144.128/25 -o vlan2 -j SNAT --to-source XX.XX.XX.XX

DNSMasq設定: DNSMasq settings

私のローカルエリアの設定(問題がある場合): DHCP settings

VPNが接続されているときにipconfig/allが表示されるもの(英語以外のコンソールでは申し訳ありません): ipconfig /all on W8 client

UPDATE1:

AndrásKorn からの手がかりを使用して、オプション2( link )の解決策を見つけました。追加した register-dnsおよびpull行のクライアントVPN構成およびinterface=tun2追加のdnsmasqオプションフィールドの行。

そして、ファイアウォール構成コマンドに3行目を追加しました。

間違ったインターフェイス(vlanXまたはethX)を使用したため、iptablesコマンドの一部が間違っていると思います。

OK、あなたの質問のインターネットアクセスの部分に関して、私はあなたの

iptables -t nat -A POSTROUTING -s 192.168.144.128/25 -o vlan2 -j SNAT --to-source XX.XX.XX.XX

間違っている。 vlan2ppp0である必要があります(ppp0はインターネットに面したインターフェイスであるため)。

次のような単純なルール

iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

また動作するはずです。
