Doubt about bridges

Hello to all.

First post on the forum!


I have 2 Bridges created A and B with a network configured on each(DHCP, NAT masq…).
Br A 192.168.2.0/24
Br B 192.168.4.0/24

I want a computer on Network A to be able to ping another computer on Network B but I can’t manage to do it with static routes.
Am I misunderstanding how to use bridges?

How should I do it if I don’t?

thanks

use firewall rule to allow it
