    Hello,

    I have a user on my network who is bypassing OpenDNS. I have the OpenDNS servers configured on my router and that works to filter sites for most of my users. However, one user has entered alternate DNS servers on his laptop and is able to completely bypass the OpenDNS settings I have in place.

    Is there any solution for this?

    thanks,
    Rod

    This has often been asked and answered here.

    Either block outbound port 53 passthrough through the router, or configure your router to redirect any DNS requests to OpenDNS, whatever your router is capable about.

    Thank you. I have the DDWRT firmware installed on a DLINK router. Looks like I shouldn't have any problem using IPTABLES to redirect the DNS requests.

    Yep, DD-WRT even have a wiki article for this purpose.

    The above link to configure you dd-wrt device is the best and pretty much the only option.

    Lets hope the individual in question does not find out about services like Hotspot Shield from AnchorFree. It operates at another layer so DNS filters are bypassed.

    Good Luck!
