  • 1.  VPN tunnel, Layer-2 or Layer-3

    Posted Jul 11, 2017 03:54 PM

    Hi all,

     

    It would be great if someone can help with a piece of advice. I am trying to send client traffic (several VLANs) from site A to site B through VPN tunnel between two Mobility Controllers. Scenario goes like this:

     

    • First MC is on site A (MC-A) and its Management IP is NATted behind firewall
    • Second MC is on site B (MC-B) and its Management IP is NATted behind firewall
    • MC-A has user VLANs added (traffic is incoming from access LAN switch that is connected directly to the MC-A, and switch ports are in access mode with user VLANs configured on them)
    • MC-B has user VLANs, and VLAN interfaces, added (reason for this is that all user traffic coming from site A will terminate on MC-B, and then be routed from MC-B to internal network)

    What would be the best VPN solution for this kind of scenario, L-2 or L-3, having in mind NATting? Thanks.

     

     

    Thanks,
