Help needed to Explain what Vlan and Tunnel Traffic is for?

Hi,

 

I am new to F5 and I am trying to configure a new virtual server. One of the parameters is the vlan and tunnel traffic, which by default is enabled on.

 

help needed here to explain what is this for? If I configure my virtual server to have virtual address in VLAN_3, and I enable vlan traffic only on VLAN-3, does this mean only requests sourced from VLAN-3 network will be accepted by F5 ltm?

 

Thank You

    That is correct. if you leave by default, traffic sourced from any vlan can connect to that virtual server. As you specify what can/cannot, it pares the list down.

    Thanks Jason.

     

    To clarify further, you meant the restriction is on the client side right? and not on the server side wherein only self-IP sourced by the Loadbalancer from Vlan-3 can get to the pool members?

    As you allow only vlan3 traffic, traffic from vlan3 will be passed to virtual server. If you specify default, all the vlan traffic can access virtual server.

    Thanks Jason. This makes a lot of sense now. I changed the vlan and tunnel traffic to default and traffic from other nets can now reach the VIP. On the other hand, if I enabled vlan and tunnel traffic, I observed it will only allow traffic that comes from that interface.
