OpenVPN with IPv6 on Client GL-MT300N-V2

[kirdneh]

Hey everyone,

I cannot get IPv6 working with my VPN (which supports IPv6).
Device: GL-MT300N-V2

What I want to achieve: Connect to VPN via OpenVPN with IPv6 support on client device.

What I did:

1. Generate OVPN-Config for a VPN with IPv6 support
2. Activate IPv6 in GUI of GL-MT300N-V2
3. Upload OVPN in GUI and connect
4. Tried to access a IPv6 only site => does not work
   Check on https://ipv6-test.com/ unsuccessful (only IPv4 from VPN)

• Connecting with the OVPN config file directly on linux does connect with IPv6
• http://192.168.8.1/#/vpnclient displays a IPv4 AND IPv6 address

Any ideas how I can get it working?

Thanks for the hints, I investigated further but cannot get it to work:

• if I ssh into the router while VPN is active I am able to reach ipv6 only sites via curl within the router
• if I execute the same curl on the client device connected via lan, I cannot reach the website

Does the client get an ipv6 address? Does the client get IPv6 routes?

This is what I see on the client when connected to the router:
