我有一个 VPS（在我家网络之外）运行着 WireGuard VPN（PiVPN + Pi-hole+ Unbound），我正在尝试设置端口转发以提高种子下载性能（就像 ProtonVPN 和 AirVPN 等服务提供的那样）。我的 Windows 10 电脑是客户端，它位于路由器后面。
我已经在路由器上配置了端口转发，但无法在 VPS 上正确运行。有人可以提供分步指南，说明如何在 VPS 上设置端口转发以实现此目的吗？
到目前为止，我已经尝试了以下方法，但没有成功
iptables -t nat -A PREROUTING -i enp0s6 -p tcp --dport 32554 -j DNAT --to-destination 10.221.178.2
iptables -t nat -A POSTROUTING -p tcp --dport 32554 -d 10.221.178.2 -j MASQUERADE
