Orbi RBR752 Mesh, Guestlan, SSH, VPN Client

Hi

I bought the Orbi Mesh Set RBR750 couple days ago. Orbi™ AX4200 (RBK752) Tri-band WiFi 6 Mesh System

I was talking with 2 different support members from netgear to precheck if my desired funktions can handled by orbi. 

And now 2 days later , none of them work. 

Thats why i write here now, i want to figure out if i have bad settings or the customer support just lying :(

First Problem: VPN Client, i try to set up a client, that my whole network uses vpn. couldn find the option. 

Second: SSH Access, i want a list of all connected devices / mac addresses, is this possible somehow? 

Third and most important: GuestWLAN it doesnt work through mesh. 

Setup: Router in the basement ground floor. Sattelite first floor. Both connected via ethernet. i have in almost each room ethernet. 

All together with Switch  Zyxel 24-Port Gigabit [GS1900-24]

I tried ethernet backhaul and wifi backhaul. 

firmware: V3.2.16.22_1.4.9 

alot of restarts.

satelite connection direct via ethernet , not through switch.

i see the the guest network on my sattelite 100% but i cant connect or if i can conenct i have no internet. 

at my groundfloor i can connect to it and i have internet. 

the most dissapointed thing, i had "only" that questWLAN problem with my "old" asus mesh system, thats the reason why i asked twice the netgear support if this really works.  

so i switched out my hardware, and now the same and more problems :-( 

sorry for my bad english, im not nativ and try my best to explain. 

I appreciate any kind of tipps to solve this problems. thank you.
