Error starting userland proxy: Bind for 0.0.0.0:4500: unexpected error Permission denied.

So, if I try to start SoftEtherVPN using Docker command

docker run -d --cap-add NET_ADMIN -p 500:500/udp -p 4500:4500/udp -p 1701:1701/tcp -p 1194:1194/udp -p 5555:5555/tcp siomiz/softethervpn

it just says

docker: Error response from daemon: driver failed programming external connectivity on endpoint stupefied_goldwasser (cc1e49e0bbae00a8001f50ae21436849f9ca26541eb65ef1b2737443070806af): Error starting userland proxy: Bind for 0.0.0.0:4500: unexpected error Permission denied.

I am using the latest Docker Hub - and SoftEtherVPN version on Windows Enterprise, port 4500 is not used by another service and I also tried executing the command by default command prompt and powershell as administrator.

I followed the setup guide located at https://hub.docker.com/r/siomiz/softethervpn/.

Unfortunately I don't have a Windows Docker environment to test this on.

• Please double-check the availability of the port 4500 (example).
• Which VPN client do you plan on using to connect? Port 4500 is only used for L2TP/IPSec so you may not need to bind it.
• On Windows systems it is probably easier to install the official SoftEtherVPN binary for Windows.
