I have 3 drayteks Vigor 2927ac. Each is other locations.
I want make site to site vpn between these 3 locations A B C /each locations colud see each locations/
I have plan to:
Site to site:
First A location draytek vpn server and two B and three C locaniotns vpn clinets /first draytek A can ping two B and three C locations/ (A could ping B C and B C could ping A) BUT B could not ping C and C could not ping B
then
on secound location B make a new vpn server and connect to it three locatin C vpn client then /- B could ping C and C could ping B/
And now ABC could ping each others .
Will it work ?
Or should I make another way ?

TO CLARIFY:
Router A
- VPN Server router A dial-in to router B
-.VPN Server router A dial-in to router C

Router B
VPN Client router B dial-out to router A

Router C
VPN Client router C dial-out to router A


Router B
VPN Server router B dial in to router C

Router C
VPN Client router C dial-out to router B
is it ok ? routers A B C CAN PING EACH OTHER? wil it work ?
