OpenVPN listen on IPv6

Hi guys,

I was just trying to create an OpenVPN Server on my RB3011.
The problem is pretty basic:

OpenVPN Server will not accept any TCP connections over IPv6.
But I CAN connect to the OpenVPN Server via IPv4.

I have firewall rules in both, IPv4 and IPv6 firewall.
The firewall rule also shows incoming packages when checking if ther port is open.

I cannot use IPv4 because my provider uses shared IPv4 addresses.

Does anyone have an idea if it is possible to do this over IPv6?
Any ideas for workarounds?

Thank you!
Best,
username2

No, if you want an IPv6 capable device return your MikroTik and purchase a router from a manufacturer capable of delivering feature needs for an IPv6 world.

It's a limitation of RouterOS and they've said it likely will not change until the mythical v7.

Thank you for your quick response!

Do you have any idea why? I would have guessed it does not matter over which protocol the package was delivered.

A logical person would assume that. MikroTik has not publicly explained why their product is in capable of binding to IPv6 addresses for most services that I'm aware of.
