如何在 Linux 上使用我自己的 pptp vpn 服务器在 Windows 中的客户端打开端口？

我已经pptpd在 Vultr ubuntu 服务器上设置了自己的服务器，我使用 Windows 内置的客户端连接到它，我成功访问了互联网，当我检查我的 IP 时，我看到的是 VPS IP 而不是我的真实 IP，但我的问题是当我尝试使用名为 的简单工具在我的 Windows 客户端中打开端口 portlistener并开始监听端口 80 时，我转到了 checkport 工具，但我看到端口 80 已关闭。那么有人知道如何在我的客户端上使用这个端口吗？

我的ifconfig命令显示如下：

iptables -L命令显示：

root@vultr:~# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)

TCPMSS     tcp  --  10.0.0.0/24          anywhere             tcp flags:SYN,RST/SYN TCPMSS clamp to PMTU

Chain OUTPUT (policy ACCEPT)

在这里找到了解决方案：

iptables 的端口转发（DMZ）

iptables -A PREROUTING -t nat -i eth1 -p tcp --dport 80 -j DNAT --to 192.168.1.50:80
iptables -A INPUT -p tcp -m state --state NEW --dport 80 -i eth1 -j ACCEPT
