I am looking for advice for something that may not be possible.
I have not yet invested in a router as I am guessing the choice will be dependant on the answers I receive. I have a spare Archer C9 (Ver 5) but it is not possible to flash it with OpenWrt so I need something else to test out.
MY IDEAL
I would like to have an OpenWrt capable router that sits between my ISP router and my WiFi Mesh router (and extenders) on a DMZ network (currently TP-Link P7 and P9 units so fully ethernet and WiFi capable).
The P7 mesh router currently manages DHCP for its network (10.0.0.0) and the ISP router uses fixed addresses (DHCP disabled) for its separate network 192.168.1.0. The 192 range only has a couple of items, the DMZ on 192.168.0.20 and a Digital to Analog IP telephone converter on 192.168.0.65.
The DMZ P7/P9 Mesh runs 2.4 and 5 GHz WiFi networks split into Private and Public access networks, the Public network being the more restrictive.
I want to be able to route some devices and their (generally static) IP addresses in the DMZ via my company VPN server and the remainder via the open internet (which may include devices that on occasion access the VPN independently through their client software). The network split between private and Public access would only be on the open internet connection side.
MY QUESTIONS
- Is OpenWrt capable of structuring such a system?
- I assume the Wrt would need to offer DHCP and replace the P7 router unit so it could revert to an extender. Is this right?
- Can it be a software only solution or would additional (to the chosen router) hardware also be required?
- What would be the best router to use for this type of setup (as WiFi capability would not be needed on the router itself)?
- Will a change from ADSL to Fibre Optic have any impact on the solution (I am guessing no but would like confirmation).
Any and all advice welcomed.
