    How do I use the Custom DHCP Options page to configure a Classless Static Route Option (option 121)?

    An example of a route that I would like to configure is 192.168.121.0/24 via 192.168.141.1. Based on RFC this route should be end up as the string '18c0a879c0a88d01' in the DHCP Offer.

    The closest settings that I have found to get this to work set the encoded type to 'uint8' and 'array'. I am then able to enter a single decimal value on each DHCP Option Value line. This seems like a very convoluted way to do this. Is there a delimiter that can be used to place the whole string on a single line? I have tried spaces, commas, and semicolons as delimiters each time I receive the error message 'Option code 121 expects type Uint8 as Scalar'.

    Using this method of one decimal value per line the next problem that I encounter is when a decimal value is reused (192 & 168) it is not accepted.

    Selecting all of the DHCP Option Value items also disables the Delete option.

    Is there any documentation on how to use this feature?

    Thanks,
