I am using NoDogSplash which is a captive portal, meaning it redirects your packets and forces you to authenticate before you can access the Internet. It does this in an isolated 10.0.0.0 network. Now, I would like to make it so that the first X addresses (let's say 32) are not managed by NoDogSplash at all, so I can put my access points and some other computers in that range.
There is a parameter called GatewayIPRange in the configuration that seems to do what I want, but I don't know what I should set it to.
By setting this parameter, you can specify a range of IP addresses on the GatewayInterface that will be responded to and managed by Nodogsplash. Addresses outside this range do not have their packets touched by Nodogsplash at all. Defaults to 0.0.0.0/0, that is, all addresses.
I know that by changing the network mask I can split a big network into smaller subnets, but as I want all hosts to have the same gateway (namely, the router the captive portal is running in), I don't think I can do this.
If at all possible, please provide a solution for the general case and/or lots of background info (or links to it, as I know this is a very elementary question).
Thanks a lot.
