Inter-communication fail when using 2 MAX BR1 using fixed IP in sequence order

Hello Support,

May i know what should i do? I setup 2 MAX BR 1 using fixed IP in sequence order by they cant reach the other side.

Max BR 1 A (Cellular)
IP: 131.202.135.58
Default Gateway: 131.202.135.57

Max BR 1 B (Cellular)
IP: 131.202.135.59
Default Gateway: 131.202.135.57

As long as all IP’s are in the same subnet mask, they should be able to talk to each other. You can open a support ticket with more details here:
