RV016 with mask?

    I have a RV016 and want to use for my network but the built-in DHCP server only supports a mask. Now I can run DHCP on one of my servers and use the RV016 as the gateway but how can I get the RV016 to talk back to my clients that have a mask?

    How does the the "multiple subnet" feature work on this router and how do I set it up?

    Any help/info would be great.

    Yeah the feature is not documented too well.

    Here's what I know and what I've done, maybe it will help...if you already know about subnetting this is probably basic, but if you don't you might want to have a look at an online IP/subnet calculator e.g. http://www.subnet-calculator.com/

    I set up the default subnet as, so
    - = network (reserved)
    - = router
    - - = hosts (some served by router's DHCP)
    - = broadcast (reserved)

    I then added a second subnet, as: /, which means:
    - = network (reserved)
    - = router
    - - = hosts
    - = broadcast (reserved)

    The non-obvious bit is that whatever address you plug in for 'LAN IP Address' in the router setup screen is what the router's address will be on that subnet. For example, I could have entered ''...the other stuff for the subnet remains as detailed above, but the router's address becomes The router does not seem to be able to serve DHCP over the additional subnets, but that's actually what you want so it should be possible to do what you're after.

    I have not experimented with it to see what kinds of subnets you can create, so I don't know whether they have to be somehow compatible or complimentary with one another. That is, I don't know whether you could do something like and then as an additional subnet.

    Curious to hear how this turns out for you...
