  • 1.  Vlan receive ip but not ping

    Posted Oct 25, 2017 04:25 PM

    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.
