I have main bridge with subnet A and 3 additional bridges with dedicated subnets - B-C-D. From main subnet i can reach any IP in other subnets with FW rule added allow traffic - seems routing here works fine. Without FW rule it does not working. Issue i have - i am unable reach any IP from subnets B-C-D with same FW rule in place. I am using default config for RB3011UiAS.
What is concept to have routing between isolated subnets? Routing? Advanced FW rules?
