Hello,

I set up 3 networks

VLAN1- 192.168.42.1/24 (default)

VLAN2- 192.168.20.1/24 (guest)

VLAN3- 10.8.0.0/20

No ACL's are set.

VLAN1 can communicate to VLAN2

VLAN3 don't have Internet access.

 

But when I try to set VLAN4 (ex. 192.168.9.1) It have Internet access. (without any ACL's- just from the WLAN manager in Omada)

What is wrong with VLAN3 settings?

it looks right so I don't know, maybe the Omada team will have to look into it

Hi @PP_,

 

Not sure if this would cause the problem, but the interface's address is included in the DHCP range. Try setting the lower bound to 10.8.0.2 or higher.  I'm actually surprised the UI even allows this.
