VPN - Zentyal to Zentyal

[MayqueSouza]

Hello,

   I have a company (matrix) with a Zentyal server that works with firewall and would like to connect with a branch through the VPN Zentyal-toZentyal.
  
   Internal network (Matrix):

WAN - 177.x.x.x.x
LAN - 192.168.0.0 - 255.255.0.0

Network (Branch)

192.168.254.0 - 255.255.255.0

   The servers talk to each other however, the branch of client machines can not communicate with the machines of the Matrix.

Does anyone have any suggestions?
   
Thank you.
