pfSense 盒子：
- 公共 IP 208.43.30.118-.117
- 私有 IP：192.168.1.1
我需要为私有网络 192.168.1.5 中的虚拟机提供 1：1 NAT 映射
我无法使 1:1 NAT 工作，尽管它应该是直接的......

我尝试设置了几次端口转发和 1:1 NAT，但流量没有转发到内部 IP。我做错了什么？
接口 外部 IP 内部 IP 目标 IP 描述
WAN 208.43.30.117 LAN 网络 192.168.1.5 转发外部到内部 ip
附加 IP 只是一个 IP 别名（虚拟 IP），在通过 GUI 上传命令输出之前，我已经添加了 1:1 NAT 规则，为什么这没有反映在发布的输出中
答案1
我犯的错误是没有配置客户端的网关指向 pfSense。
nat 客户端有多个网卡，并且默认网关设置为另一个网卡。
一旦修复，问题就解决了
