I done it, im created bridge for both side ( ZS LAN + VPN00 )
It connected pretty well & can play game 2gether without laggy or delay.
The ZS A is connected to ZS B, now i wanted to build one more ( ZS C ), i tried use the same way mean using same Preshared Key as ZS A & ZS B, but cant connect to the ZS A at all.
Is it not allowed to add more Client to the Server? It just allow for one client??
Thanks a lot for you helpfull comment..
