Hi,



I am part of a small startup shipping container office park, there are 5 of us. We are sharing one fibre connection to the internet between the 5 of us via a Fritzbox fibre router. I am trying to set up the network and I before I do anything I wanted to ask if what I had planned would work.



  1. I want each office router to provide their own IP addresses via DHCP to all equipment within their office
  2. I want to the router in each office to be connected to the Fritzbox fibre router via ethernet for internet access
  3. I want to Fritzbox fibre router to only talk to the 4 routers connected to it, I presume by allocating fixed IPs and using the mac address or can it be done via IP?
  4. I am not too sure of the IP addresses to use, do I just use the Fritzbox fibre router as the gateway for the other 4 routers?
  5. How do I then set those routers up to have a fixed ip on the Fritzbox fibre router but give out their own IP addresses ideally in another range to avoid conflicts with the Fritzbox fibre router and each other?
This is a network diagram attached and a very bad guess at what I think the IP addresses can or should be.....

Any assistance would be greatly appreciated



Kind regards

Hi Guys

Thanks for responding so quickly - I suppose the issue is that they all already own different routers and they want to use them if they can, at the moment, they are just plugging their router via ethernet into the Fristzbox but its causing loads of conflicts like 192.168.0.1 is appearing multiple times and causing conflicts, some of them have equipment that is telling the fritzbox it's in germany and that's causing conflicts, what I wanted to do was to lock down the network, give each office an ethernet connection via a fixed IP and let them look after any internal conflicts internally, as at the moment it's bringing the whole network into problems when IPs are conflicting, so I thought, one fibre router, 4 routers plugged into that, give permission to the Fibre router to only talk to the fixed IP on the other routers and that would limit the fibre router to 4 connections only, if there were IP conflicts on Office 3's network for example, it's not going to impact anyone else....this is all a little bit beyond me though and we have been trying for months to get someone to come and look at it but they keep promising and then not showing up!!!
