QUIC VPN Protocol

Adguard VPN (not Adguard Ad blocker) uses QUIC protocol. Are GL routers able to run this protocol? I have found it useful in some regions.

No, QUIC is not supported.

Is there any plan to support QUIC protocol?

Not planned yet. It seems only some browsers and specific VPN applications implement this, and it is not clear about the improvement of using QUIC on VPN.
