At the moment I have both LAN1 and LAN2 utilized however I can not talk across them. 

My configuration



LAN1 =

LAN2 =

LAN2 =



Computer 1 =

Computer 2 =

Computer 3 =


If I try and ping the Unifi Security gateway on any computer I can reach it, for example.


Computer 1: IP: 

If I try to ping or I can ping the Unifi Security Gateway, however If computer 1 tries to ping computer 2 it can not ping it, same thing with attempting to ping computer 3. Computer 1's gateway is (Unifi Gateway) Computer 2's gateway is


I thought by default I would be able to ping across the "corporate" networks but I can not. 


Any help is appriciated.
