Guidance on connecting networks via ISP router and your own router
It seems you're dealing with a network setup involving two routers and a switch, but you're facing issues with port forwarding for your UNRAID server. Since you can't access the ISP router's interface and it's not working across all devices, here are some possible steps:
- Check if the ISP router is properly connected to the switch and if the subnet settings match.
- Try connecting the device directly to the ISP router using a wired connection.
- Ensure the ISP router is configured to forward ports correctly for your UNRAID server.
- If possible, consult the ISP support or check their documentation for troubleshooting tips.
Having two (consumer) routers on the network causes problems at the best of times. Without being able to configure one is simply not going to work well. They're on different subnets, which is why you can't access anything connected to the ISP router from the TP-Link router and vice-versa. You can move the TP-Link router to the 192.168.1.0/24 subnet (assuming you're using the LAN ports on both routers to connect them, not WAN) and that would allow you to access things connected to both, but you'd then start running into potential DHCP conflicts. As you can't configure the ISP one, no matter what IP you assign to the TP-Link, there's always a chance the ISP router will assign that IP to another device. You'd also need to disable a bunch of features on the TP-Link to avoid conflicts, at which point there's no point in having it. I'd contact your ISP for details on how to configure the ISP router. Ideally, ask them how to set up the TP-Link to remove theirs, assuming they're an ISP that will let you and that it's not a modem/router combo while the TP-Link is not. If you need to have the ISP router for whatever reason, I'd advise getting rid of the TP-Link one as there's no point in having it, it will just add needless hops and issues to the network. If you have it for wireless, buy an access point instead as that's the only thing you'd need. EDIT: As long as the ISP router is serving as the border gateway for you network, any port forwarding for your UNRAID will have to be done there. TP-Link router will only see the local IP from the ISP router without any config on the ISP one.
An ISP might permit third-party modems, yet you must confirm with them first.
However, if you can't set it up, the ISP will keep handling NAT, DHCP, DNS and other tasks. Even after relocating the TP-Link device to the ISP's network segment, you'll likely need to turn everything off and switch it to AP mode, since any additional functions could create issues.
