我的任务是设置端口转发以访问服务器上的远程桌面。但我遇到了麻烦。
服务器IP 192.168.1.20，端口3389
路由器是 Cisco SR520。它位于我们 ISP 调制解调器的后面，调制解调器的 IP 为 192.168.5.1。他们的调制解调器的 NAT 应该将传入连接发送到 192.168.5.100（这是该接口 FastEthernet4 的路由器 IP）。
我们确实有几个 VLAN，服务器位于 VLAN 1 上。
我不是网络方面的专家，只是初涉网络。我相信 NAT 已配置为正确转发端口，并且我添加了访问列表规则以允许它。还有一些区域安全，但我不确定。这看起来正确吗？我遗漏了什么吗？
