无法访问连接到 OpenVPN 服务器的网络

无法访问连接到 OpenVPN 服务器的网络

VPN 服务器 (Linux) 位于路由器后面。我想从外部网络连接到我的 VPN 服务器并访问服务器本地网络中的设备(以及服务器本身)。

本地网络的地址范围是 192.168.178.0/24

我也将一些端口转发到了我的 VPN 服务器:1194、80、21、443、1723

!!由于已达到体量限制,我删除了之前的信息!!

编辑4:当前设置的完整列表:这是我的服务器配置:


port 1194

我的客户端配置如下所示。

我的服务器接口配置如下:


auto lo

allow-hotplug eth0

auto br0
iface br0 inet static

netmask 255.255.255.0

iface eth0 inet manual
up ifconfig $IFACE 0.0.0.0 up
up ip link set $IFACE promisc on
down ip link set $IFACE promisc off
down ifconfig $IFACE down

还有我的 rc.local


iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -t nat -A POSTROUTING -j MASQUERADE

我的 sysctl net.ipv4.ip_forward 输出是 net.ipv4.ip_forward = 1

我的客户端日志输出如下:

Sat Sep 13 17:36:11 2014 us=76308 GET INST BY REAL: 86.103.202.242:55140 [failed]  

也许这能有帮助!?

答案1

您的客户端文件缺少远程服务器的 IP 地址以及用于联系服务器本身的端口指示。换句话说,您缺少:

 port 1194
 remote IP.ADDRESS.OF.SERVER

另外,我不明白为什么您要为客户端使用子网 10.8.0.0/24。您已经选择了轻敲桥接 OpenVPN 的接口(不错的选择,可以更轻松地访问 LAN 上的所有 PC,且无需额外付费),因此无需使用不同的子网。您的服务器文件应包含以下语句

 server-bridge 192.168.178.1 255.255.255.0 192.168.178.111 192.168.178.120
 push "route-gateway 192.168.178.1"
 push "redirect-gateway def1 bypass-dhcp"
 push "dhcp-option DNS 192.168.178.1"
 push "dhcp-option DNS 208.67.222.222"

第一条语句指示服务器在 192.168.178.(111-120) 池中为远程客户端提取 IP 地址。只需确保您的 LAN 上的 DHCP 服务器不会尝试自己使用这些地址,在这种情况下,您必须为 OpenVPN 池选择不同的池。其他语句显而易见。

最后,除了上述声明之外,没有必要定义单独的路线。

编辑:

您需要更改 iptables 并在服务器上建立桥接。

  1. 将您的 /etc/netorking/interfaces 文件更改为如下所示:

    自动 lo iface lo inet 环回

    自动 br0 iface br0 inet 静态地址 192.168.178.123 网络掩码 255.255.255.0 网关 192.168.178.1 bridge_ports eth0 dns-nameservers 192.168.178.1

    iface eth0 inet manual 启动 ifconfig $IFACE 0.0.0.0 启动 启动 ip 链路设置 $IFACE promisc on 停止 ip 链路设置 $IFACE promisc off 停止 ifconfig $IFACE down

重新启动服务器以使此操作生效。检查服务器是否正确连接到互联网。然后按如下方式更改 iptables 规则:

 iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT  
 iptables -t nat –A POSTROUTING -o br0 -j MASQUERADE

启动 OpenVPN 服务器,并将 tap0 接口添加到网桥,

 sudo brctl addif br0 tap0

现在尝试从客户端连接。

编辑2:

此 iptables 规则

 iptables -t nat -A POSTROUTING -j MASQUERADE

应该

 iptables -t nat -A POSTROUTING -o br0 -j MASQUERADE

另外,请使用tap0代替轻敲在服务器配置文件中。请重新启动并通知我。
