V2ray报如下错误：
listen udp 0.0.0.0:60003: bind: An attempt was made to access a socket in a way forbidden by its access permissions.

原因：Hyper-V保留了一些端口，包含这一端口

1.查看系统保留TCP，UDP端口

netsh interface ipv4 show excludedportrange protocol=tcp
netsh interface ipv4 show excludedportrange protocol=udp

2.关闭hyper-v，重启

dism.exe /Online /Disable-Feature:Microsoft-Hyper-V

3.再次查看系统保留端口

4.查看需要自定义保留的端口是否已被程序占用

netstat -ano

5.设置自定义保留端口

netsh int ipv4 add excludedportrange protocol=tcp startport=60000 numberofports=500
netsh int ipv4 add excludedportrange protocol=udp startport=60000 numberofports=500

6.若需删除配置项

netsh int ipv4 delete excludedportrange protocol=tcp startport=50051 numberofports=1
netsh int ipv4 delete excludedportrange protocol=udp startport=50051 numberofports=1

7.打开hyper-v，重启

dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All
