我设置了 proxmox 实例，一切运行正常，但我遇到了端口转发问题
我有：
服务器A公共 IP 为 1.2.3.4，其专用服务器为 (proxmox)
服务器B（服务器 A 上的虚拟机）桥接 IP：10.10.10.7
我的目标是路由 1.2.3.4:5022 -> 10.10.10.7:22
我的网络配置

# If you want to manage parts of the network configuration manually,

# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

telnet 10.10.10.7 22作品
telnet localhost 5022不起作用
telnet 1.2.3.4 22不起作用
有人能帮我吗？我想学习网络知识，但找不到相关内容
