Question Is it possible to have a 10.x subnet within a 192.168.x network?

[Goi]

Hi,

I have a home network where the main router is configured with a 192.168.x IP address, and other routers that are connected to it are set to bridge/AP mode to get IP addresses automatically assigned via DHCP.

Due to certain requirements, I now want to have a 10.x IP address instead on a specific device which is connected to one of the sub-routers. If possible, I would like only that subnet to have a 10.x IP address, while maintaining a 192.168.x for the main router.

Is this at all possible?

 

[mxnerd]

Yep.

should note that u will not see computers on cross networks, unless you have a PC with dual nic's connected to both networks.

 

[Goi]

Yep.

So how do I do that? Manually set the IP address for the sub-router to 10.x and disable DHCP there?

 

[mxnerd]

Set the LAN IP in 10.x.x.x range and enable DHCP for the router.

Then uplink 2nd router's WAN port to main router.

Weird, seems like my D-LINK doesn't allow manual setting of LAN IP addresses.




Even though D-Link says it can here - https://www.dlink.com.sg/how-do-i-change-the-ip-address-of-my-dir-868l-router/

Maybe because I'm in Wireless AP mode? I'm in Wireless AP mode as the DIR-868L is a leaf router that's connected to the main router (a Linksys EA7300).

You need to change it back to router mode.

And what does Manual Internet Connection setup at the bottom mean then?

 

[aigomorla]

uhhh... op to be honest, i would leave it alone if you do not even know how to navigate though your router, and it being dlink consumer, should be pretty straight forward.

The reason for it is because you need some knowledge in how to change the scope of your DHCP server built into the router.
If your getting stuck at the front page, my advice, don't do it, or ask someone like a friend who has some network knoweldge to come over and set it up for you, because i see you pressing that reset button many many times from bricking your network by having 2 dhcp servers fighting for the same subnet.

That lets me set the WAN settings, not the LAN settings. From the documentation if I want to use it as a secondary router, it should be set as a Wireless AP, which is what I've done. If it's back to router mode, would I be able to use it as a secondary router?

I know how to navigate the router's admin portal, but I think the LAN settings aren't available in Wireless AP mode. I have some basic networking knowledge, and what I don't know, I know enough to google.

yes.

But as what aigomorla has said, if you don't know what you are doing, don't change the setup!

What exactly was reason that you want to put a device behind 2nd router's LAN range? You will not be able to access that deivce from 1st LAN.

A lot of users worry too much about their PC/device being hacked and want to put some devices on another LAN,, and that creates a lot of problem, not solving them.

I have a device that will only connect to a 10.x network, not a 192.x one. I would change the entire home network to 10.x, but thought it'd be easier to test it on a subnet first so I don't affect the rest of the network.

that makes no sense... it has no dynamic ip feature? Do you know the static ip for the device? if it has no dynamic ip feature, you won't be able to get into the config mode without knowing the static IP.

What is the device?
Is it like a camera? a Access Point? a managed switch?
Are you trying to get into the device's config portal?

There are easier and better ways to do so, you get a PC, and set a static IP on the network card and put it on the same ip scope to get into config so you can change the ip scope of the device manually.

This!

Not sure what his application is, but I've seen a disturbing number of 5 and 6 figure scientific instruments that have fixed IPs and no user settable means of changing them. It's a huge PITA.

It's a laptop with an endpoint security product that only allows outgoing SMB connections to 10.x IP addresses. Anyway, if I were to change the main router to 10.x IP address, assuming the sub-routers have DHCP enabled, everything should be automatic right?

If that's the case, then the preconfigured laptop should connect to the router that has 10.x range, whether it's 1st or 2nd.

The best way is just change both your main router and AP's LAP IP addresses to 10.x range. Why would it be so hard?

If you change your AP back to router mode and change it's range to 10.x , your wifi devices that connect to the AP will also have the same range as your laptop.
