Can openmptcprouter be successfully used if VPS only has IPv6?

[RabbitJun]

As is well known, openmptcprouter works well with IPv4 VPS. So if VPS only has IPv6, can Openmptcprouter be successfully used? How to configure openmptcprouter? What are the changes from the usual configuration method? Thank you for your response

[Ysurac]

Yes, but it's less tested. You only have to set IPv6 only.
If your VPS provider doesn't support DNS64/NAT64 then you have only access to IPv6 address.

[RabbitJun]

Thank you, I will try. IPv6 will become increasingly popular, I believe.

Did I do something wrong? The Wan6 router can ping the VPS, but the displayed IP is not the VPS IP

[Ysurac]

You can ping IPv6 server's IP via SSH on the router ?
You need also to disable 6in4 in System->OpenMPTCProuter, "Advanced settings" tab.

[RabbitJun]

Yes, I have tried all these options but still couldn't get the VPS IP. This must mean that I didn't succeed.

[Ysurac]

What is the result of ip -6 r ?

[Ysurac]

curl -k -6 https://[<vpsip>]:65500/ ?

[RabbitJun]

curl: (7) Failed to connect to...

Okay, I know what the problem is now.

I checked the port on VPS. 65500 is not running on tcp6

[Ysurac]

True, it should. Seems that I have an error in my script.

[Ysurac]

Should be fixed in snapshot script: wget -O - https://www.openmptcprouter.com/server-test/debian-x86_64.sh | KERNEL="6.12" sh

[RabbitJun]

root@Router:~# curl -k -6 https://[ipv6]:65500
"Welcome to OpenMPTCProuter Server part

But the router still can't get the VPS IP, but I have a feeling that it's about to succeed

[RabbitJun]

I have tried various protocols, whether it's v2ray, ShadowSocks, or mptcp over VPN, they all can't get public IP. I suspect this may be the final malfunction, perhaps taking a step forward would be useful.

[Ysurac]

Stay on shadowsocks-rust with OpenVPN as VPN, easier to debug.
Can you give me, via SSH on the router, the result of ip -6 r and logread ?
And on the VPS, the result of curl ip.openmptcprouter.com and of journalctl -u shadowsocks-go ?

I used the command to get txt, and the content is all in the attachment
