Establishing a TCP-Connection to a server with IPv6 router

[clash]

Hi,

my server is running behind a router with IPv6 so I can not use port forwarding here.

SoftEther VPN keeps telling me that I only have an UDP-Connection and I should establish a realiable TCP-Connection.

But how can I do this without port forwarding?
Any solution here?

Thanks,
c.

Is there an IP forwarding function on that router?

I did not know that Softether supports an IPv6 Host Name, so this should be no problem anymore.

But I have another one now: Is there a way to connect to an IPv6-SoftEther-Server when I only have an IPv4-SoftEther-Client?
I already tried but I get an error which says I should check the host name and port number..

There is a way.
However, you need a relay host that can communicate with the VPN server and the VPN client.
