This cannot be that onerous, however I have been beating my head on this for days. Somebody please inform me what I am doing improper.
I’ve a house community utilizing two ASUS routers that create two separate subnets. (I’ve a topology diagram, if I can work out how you can publish it.) Briefly, Router 2 (R2) connects to the web, and Router 1 (R1) connects its WAN port to a LAN port on Router 2, with static IP. Each routers present a couple of DHCP addresses of their respective subnets. Router 2 is my IOT subnet and has an NVR plus a bunch of hard-wired IP cameras, plus Residence Assistant. Router 1 is my “main” subnet. It connects a PC, TV and a file server. I’ve a static route between R2 and R1, and that has allowed the entire cameras to make use of the NTP service offered by a Synology file server on R1. Firewall is enabled on R2 and Disabled on R1. I can hit exterior (exterior web) web sites from a PC related to both R2 or R1.
Every of the IOT gadgets on R2 present an online server for administration. I can hit any of these internet servers utilizing their R2 static IP addresses from a PC related to R2.
Now, the issue. I might like to have the ability to at the least view these gadgets from the PC on my main subnet (R1). That’s, I have to hit these internet servers on R2 from a PC on R1. I can not seem to discover any strategy to accomplish that. Sure, I may put all the things on one subnet, however the objective is to maintain the IOT visitors by itself subnet. Is there some routing or port forwarding or one thing I am lacking?
