ISP provides 13 static WAN IPs in location A. The nature of the ISP's endpoint equipment is, if  a device with one of the static IP's is connected, it works. If a device request an IP via dhcp, they issue an address via dhcp, on their own IP address. This dhcp server cannot be disabled. Previous endpoint equipment had a port with no DHCP.  At location A, we have two physical networks, and two routers, each using one static WAN address. One for our business, (172. ips)  and one for customer network.
There is a wireless bridge between location A and location B.  At location B, we distribute to 5 more locations wirelessly, but each of those has a static IP from the range, with their own router. We also have the main internal server for our business, at location B.
We have a network cable from the 172. network, and from the port on the ISP endpoint, in a switch that is also connected to the wireless link to location B, thus providing WAN IPs and 172. IPs for the business equipment. However, that makes two DHCP servers on the same network, and after a few days, it all collapses. Previously, I had hooked up a small Mikrotik device, in the line coming from the ISP equipment, that blocked DHCP offers, and that worked, but it seemed not "snappy" for lack of a more technical description. That box died the other day, so now the problem is back, and I would like to make it as efficient as possible, without spending a fortune. I need advice on whether to just go back to blocking the undesired DHCP server, or use VLANs somehow ( I have switches to support that, but am unsure how to best use them), or put another router at location B, and then VPN back to location A for business network. Or a better simpler solution...
