Wireless Bridge two different subnets using 2 Ubiqiti NanoBridge M5

Hello,

I have two wireless Ubiqiti NanoBridge M5’s and am trying to configure a bridge to work on two different subnets.

Building A has a subnet of 10.1.1.x.

I assigned NanoBridge A with 10.1.1.15.

Building B is on subnet 10.1.10.x

I don’t know what to assign NanoBridge B to be able to work correctly.

I need guidance in how to configure the IP address\ Subnet on the Ubiqiti devices. I have two buildings each with it's own subnet.

Again,

Building A is on subnet 10.1.1.x

Building B is on Subnet 10.1.10.x.

My question is how do i configure the Ubitiqi devices network information. Do I set one up with 10.1.1.20 and the other 10.1.10.20? Or do I set a VLan, IP address alias or ???

In a small room I can get them to talk to each other just fine if they are both on the same subnet.

NanoBridge A 10.1.1.15 and NanoBridge B 10.1.1.14 work flawlessly.

How do I configure them to work on two different subnets on the same domain?

Thank you so much for any information.
