Hello,
I'm configuring my new networking setup and I've came across a strange VLAN behavior:

I have 2 LANs configured: the LAN (default) with suvnet 10.144.1.1/24 with vlan ID 1 and a second VLAN called IOT with ID 20. It is configured as Interface and with separate subnet 10.144.20.1/24.
I have not configured any ACLs yet.

I can ping devices in VLAN 20 from VLAN 1 but I cannot ping devices in VLAN 1 from VLAN 20. At the same time I can use other services of VLAN 20 from VLAN 1 e.g. SSH.

Is that a limitation of the gateway or I need to configure something more to make it work?

The ping would be useful when configuring ACLs as otherwise it is hard to say when they work and when not.
