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.

Eureka! This was client's issue not the router. Aparently Windows Firewall is blocking by default ICMP requests when they are coming from a different subnet...
