    Hi,

     

    Is it feasible to put a wireless controller inside the DMZ? Any implications? Highlight any limitations?

    In my case, the DMZ comprises of 2 firewalls and 1 cisco switch (in between)

     

    Regards,

    Suggestforme,

     

    Very few people deploy controllers in the DMZ, because of the complexity.  It is much simpler to deploy it internally.  We typically only DMZ deployments  in high-security environments like banks where it is their policy.

    Hi cjoseph,

     

    Having solved the placement of the controller, now the customer want to establish a link (allow Aruba controller from Country A communicate with Country B),

     

    Can Aruba controller supports IPsec tunnelling VPN?

     

    How does controller in Country A and Country B communicates? What is involved in this case?

    Please advice.

    Aruba controllers , can act as a VPN routeur, for your case you need a public IP addres from each way.

    you can find more specific info in here with respect to setting up a site-to-site VPN.

    What does the customer want to accomplish?  What is the main goal of the controllers communicating?

    Hi cjoseph,

     

    The purpose of the two controllers communicating such that:

    Users in Country A goes to Country B for conference or meeting etc. Users (in Country A) will access the Wi-Fi (authenticated to AP) in Country B and join the network of Country B.

     

    Hope this clarifies.

    SuggestforMe,

     

    Do you have any other wired traffic that functions like this?  For example, does the wired traffic have an ipsec tunnel from site a to site b?

    Hi cjoseph,

     

    Yes, IPsec tunnel do exist from one site to another site.

    In a campus deployment the natural place of the controller is the inside zone especially because it have integrated statefull firewall (if you have the PEF-NG licences).

    But if you are deploying the controller to work with remote AP outside of your network, the DMZ zone will be more suitable for the controller
