    Hello there, happy new year for everyone.

    I made a configuration with 2 VLAN but it did'nt work. I can not ping through other vlans ...

    My switch is a HPE OfficeConnect 1920S 24G 2SFP PoE+ (370W) JL385A

    My exact configuration : 

    SETUP NETWORK : 
    > Get connected 
    IP ADDRESS : 192.168.1.50
    SUBNET MASK : 255.255.255.0
    
    VLAN CONFIGURATION :
    
    VLAN 100 
    VLAN 200
    
    PORT MEMBERSHIP : 
    1-12 / VLAN 100 INCLUDE UNTAGGED
    13-22 / VLAN 200 INCLUDE UNTAGGED
    
    ROUTING : 
    > GLOBAL 
    Routing Mode : ENABLE
    > VLAN /Interface Configuration
    VLAN 100 :
    Routing Mode : ENABLE
    Admin Mode : ENABLE
    IP ADDRESS CONFIG : MANUAL
    192.168.10.254
    255.255.255.0
    
    VLAN 200 :
    Routing Mode : ENABLE
    Admin Mode : ENABLE
    IP ADDRESS CONFIG : MANUAL
    192.168.20.254
    255.255.255.0
    
    

     

    I plug 2 computers on the switch.

    Computer 1 :

    Port : 3

    IP : 192.168.10.1

    Netmask : 255.255.255.0

    Gateway : 192.168.10.254

     

    Computer 2 :

    Port : 15

    IP : 192.168.20.1

    Netmask : 255.255.255.0

    Gateway : 192.168.20.254

    Thank you

    Im a student in network and telecommunications

    If routing is enabled on your HPE OfficeConnect 1920S and VLAN configuration is what you wrote (ports 1-12 are all untagged members of VLAN id 100 and ports 13-22 are all untagged members of VLAN id 200)...and if VLAN 100 and 200 have been configured with proper SVIs (IPs Addressing) then your configuration should work out-of-the-box: so check (disable!) the OS Firewall at host level and repeat your inter-VLAN routing test between your hosts.

    An host with 192.168.10.1/24 (and Default Gateway 192.168.10.254) connected on any port in the range 1-12 should be able to successfully perform an ICMP Ping against an host with 192.168.20.1/24 (and Default Gateway 192.168.20.254) connected on any port in the range 13-22 and vice-versa.

    @parnassus thanks for your help.

    The problem was the firewall. To test, I've completely disabled the firewall on both my machines.

    And the two of them started ping each other.

    Now my vlans can ping each others but i have an other thing to do.

    I need to give acces to the internet to all of theim.

    Here's the configuration I need to set up : https://imgur.com/a/3hIioNd

    How should i process ?

    I know I'm gonna have to use a trunk link, but I've never done it on switch HPE graphic version. I only did it with cisco command line.

    Thanks

    In order to access internet you have to add a default rout towards your internet gateway 192.168.1.254. But keep in mind that the gateway is doing NAT for you private address configured in static vlans. 

     

    You can refer below document to know how to add a default rout in 1920 switch.
