Switching DHCP Back to Server from SonicWALL

Posted on 2011-10-02

Hey Everyone -

I currently have a client that is using their SonicWALL TZ100 to provide DHCP and DNS services to their network. After talking to a few people, I've come to idea that it's probably best to keep more services on the server than the router.

Just setup the client with a new SBS 2011 box and I figure this is the time to make that change. Will I be losing anything by switching? Before adding any clients to the domain,  I currently turned off DHCP server on the SonicWALL and turned on the SBS 2011 box. Also created the scope as well. Will anything be affected (like their content filtering service on the SonicWALL) by making this switch?

    No, nothing will be lost. HIWEVER you should stick to the Zsbs wizards. For examp,e, you mentioned setting up the scope. The benefit f putting DHCP on SBS is the ease of configuration of both the server and clients via the wizards. Setting up a scope manually is unnecessary, and in fact can create inefficiency if even one minor setting is missed or misconfigured. The SBS wizards set ip the necessary DHCP scope for you.

    Make sure to check DHCP range on the firewall for VPN clients as I believe vpn clients that are assigned static addresses must come from the sonicwall.

    I don't know how it looks like in SBS but it non-SBS edition you shouls also enable "Conflict detection attempts" to 2 or 3
    to prevent issued IP addresses conflict and rebulid your DHCP database.

    This option is on advanced tab of DHCP server (in non-SBS edition)

    Also you have to recreate each DHCP reservation for workstation on a server because they were not put there automatically.
