I have asked questions about this complex in the past, but now my questions are changing a bit.
Right now we have an apartment complex that has about 30 units that have the offering to get free high-speed internet through us. We have a 20mb pipe from Comcast that comes in to one of their comcast business modems/routers. What I was thinking about doing is getting each apartment their own router. Then I would turn off DHCP on the Comcast router & assign each router a static IP address in its own subnet. (ie - apartment 1 would be 192.168.1.1 with DHCP range of 192.168.1.10-20, apartment 2 would be 192.168.2.1 with DHCP range of 192.168.2.10-20). I have a few questions:
1) Will that work to give each of them an internet connection that is separate?
2) Will traffic be allowed between routers? (ie if there is a virus or someone is being malicious)
3) Are there any downsides to doing this?
Secondly, the idea would be that I can control all of the individual routers from a computer that has a static IP address on the main Comcast router (ie 10.1.10.200) - will that be possible? That will allow me to go in & remotely shut off someone's router settings if they are not paying their rent.
Thirdly, each of the individual routers will have WiFi too with their own SSID & WPA key, will I have issues doing that? (conflicts etc)
I know that it's a bit of work to set up from the get-go, but the primary reason we're looking to do this is to prevent users from getting their own router & plugging in whatever they want & however they want. (ie - we had one user that plugged in their QWEST DSL modem with router into the network connection we provided in their apartment & voila, it became a secondary DHCP server that screwed everyone up)
I know that there are much more intricate ways to do this, but keep in mind that it has to be VERY budget restrained as it is just a free internet service, please stick with my general plan or something similar.
