How internet services can work in VLANs if there are 4VLANs on X440x Switch.


Greetings!

Dear Friends,

We created 4 VLANs in X440x switch on which default VLAN1 is getting Internet service while other 3 VLANs are not having internet service.

We can provide further information if you need.

Thank You!

Best Regards

enable ipforwarding would enable it for every existing VLAN (for IPv4), no need to specify it for every vlan afterward, unless you create a new VLAN.

You need to have an IP address on each VLAN, that would be the gateway for your users. Pay attention to the limited L3 scale (ARP, routes) of the x440.
That would be my guess

Do you want to use an DHCP service on the Internet Router as well? If yes you should also get familiar with the EXOS command regarding bootp relay. http://documentation.extremenetworks.com/exos/EXOS_All/IPUnicast/c_managing-dhcpbootp-relay.shtml#i994216 In all cases you will need the already mentioned interVLAN Routing: https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-enable-inter-VLAN-routing-in-EXOS Cheers, Jan

Once you apply an IP address and turn on ip forwarding you will need a default route configured as well:

You will likely need routes back to be added on the firewall as well.
