DHCP option 234 issue with AP

akqadm
Hi,

i have some problems with my AP´s ( 10 and 30) and DHCP Option 234(Magic IP)
I need to change this IP because I can´t route it in my environment.

If I do understand DHCP correctly a DHCP Client has a predefined list of DHCP options it can ask for.
So when i configure my DHCP server to rollout this option the client should grep it.
But when I look into Wireshark-Trace from the DHCP-Discover of the AP then I do not see an option 234 , 73 or 74.

So what will be a solution for me? Can I somehow program the AP to ask for this option? Or do i somehow need to reflash the AP with another firmware?

Kind regards

    The AP10 and AP30 work only with Sophos firmware - you might "kill" them by flashing another manufacturer's firmware.

    I would suggest that the Sophos UTM DHCP server should be used with Sophos APs although the ASA's DHCP server should work. Here's the KnowledgeBase article that you need: Using DHCP to get the IP of a Sophos Access Point

    Cheers - Bob

    So finally I got it working.
    But I didnt went for the DHCP option.
    I realized it via a NAT rule where I manipulated the 1.2.3.4 to the IP address of the UTM.

    Btw it is also a bug of the cisco ASA that it can´t provide the option 234 [;)]

    nonetheless thanks for your help [:)]

    Hi, How did you do it? I have the same problem..this time i'm using pfsense as the dhcp server..and I also define DHCP Option 234 on it but no luck, the utm wont detect the AP30

    Thanks in advance!
