Sophos AP50 DHCP

Hello,

It seems that I cannot connect to my WAP when using mobile devices or WiFi. It recognise my wap, but it keeps saying 'Searching for an IP address'. Sorry if this is incorrect, because I use Dutch devices. But the DHCP cannot be reached. What can I do? Can I use tcpdump on my UTM? A tcpdump for my DHCP server, which is located on a Windows Server 2008 R2? Or Wireshark to investigate my eth?

Many thanks in advance,

Nikolai Wolf

  • In that case you should have a guest interface. If you want your 2k8 server to hand out DHCP addresses it should have a scope for this subnet and the router (probably the UTM) should act as a DHCP-relay to forward DHCP-requests to your 2k8 server.
    Easier in this case is to setup the UTM to act as DHCP-server for this subnet since it most likely already has an interface in this subnet.

    Managing several Sophos UTMs and Sophos XGs both at work and at some home locations, dedicated to continuously improve IT-security and feeling well helping others with their IT-security challenges.

    Sometimes I post some useful tips on my blog, see blog.pijnappels.eu/category/sophos/ for Sophos related posts.
