Did they mess up on the naming of this release?
The beta version is: 220.127.116.11_386_57317
I am currently on 18.104.22.168.386_45934
To jump 6 full feature versions is unliekly.
New VPN client interface
Clients can be assigned to a specific VPN profile. This function is similar to VPN fusion. (AX models' features).[/QUOTI ]
I'm not sure if this is why someone purchased an RT-AX89X expecting/hoping it supports VPN Fusion, but it doesn't. (I think it is "GT" models specifically. I haven't seen a GT that doesn't support VPN Fusion yet).
EDIT- I noticed recently ROG GS series routers offer VPN Fusion, also TUF series.
