Vlan receive ip but not ping

[JesseGVanico]

Hi,

I have 3 Vlans on a test environement.

Vlan 1 is my default and my dhcp is on it. Vlan2 and Vlan3 receive ip from dhcp on Vlan1. When i plug a device on a Vlan i receive ip from the server with the good range and i see the device on the dhcp.After that i try to ping ip from other vlan and it not working. Inter Vlan communication not working but in my firewall i autorise communication.

My firewall (watchguard firebox t30) have interface with my 3 Vlans with dhcp relay to my dhcp server and i have hpe 1820 layer 2 switch with port configuration for my 3 Vlans.

I do not understand why I receive an ip from my server, but after I can not pin the server or another ip on my 3 Vlan.

Thank you.
