ARUBA IAP-207

  • 1.  ARUBA IAP-207

    Posted 23 days ago
    Hello,

    I have an Aruba IAP 207 with the following configuration:
    SSID 1 which is set to take the IP from the Server of the DHCP Windows
    SSID 2 for guests and it takes its IP address from the Aruba IAP-207 DHCP

    The problem is that I changed the old firewall with a new one from Cisco (Firepower 1010 FTD) and the Aruba IAP 207 doesn't work anymore (DHCP doesn't work, I don't have internet access)
    What should I do, so that the IAP 207 takes the DHCP client from the Server and internet access too?
    The old firewall does not have a special setting for ARUBA IAP 207.
    When I put them (IAP-207) into operation I did not set anything on the firewall, I only configured them as it is written in the documentation.
    It doesn't work with the new one.

    Appreciate your help

    Thanks

    Hi Gerald.

    check to see if DHCP relay is permitted on the firewall (UDP 67&68)

    Hi Bhavin,

    Hi Gerald,

    when I get it right you are having issue with SSID 1 to get a Clients IP Address via DHCP - correct?
    What you have changed is the Firewall and I assume that there will be the source of the issue.
    Is the Firewall between the DHCP Server and the AP? If so the Firewall will drop the DHCP Requests of the Client. The IAP will forward the Request by the Client to the Layer 3 component - this could be the Firewall in your case. Here is the IP Helper Address configured - this is something to check. The Firewall forwards the request to the DHCP Server which is offering this back to the Client.

    Cheers
