How to have Windows 10 server connect on IPv6 address

[panluowei]

Hi,

I have a dual stack (IPv4 and IPv6) Windows 10 NoMachine Server. Clients can connect fine to NX:, but not the ipv6 address. Is there something special that needs configuring on the server?

BTW, this works fine with a Linux NoMachine Server (i.e. clients can connect to NX:, NX:, SSH:, and SSH: with no problem.

With firewall disabled an “nmap” shows the Windows 10 only listening on the ipv4 ports, and the linux system listening on both (see below). How do I get the Windows 10 to listen on the ipv6 address?

thanks

After troubleshooting, I don’t think this is a NoMachine configuration question. I think it is a Windows 10 ipv6 dns lookup issue.

We couldn’t reproduce such problem in our lab. It’s possible that is system configuration issue. Can you run debug, reproduce problem and send to forum[at]nomachine[dot]com? You can find instructions about collecting logs here: https://www.nomachine.com/DT04M00076.
