I can't connect to IP cameras when I'm on the network, but I'm perfectly fine when not on the network.

tmli · Jan 8, 2017

Hi! I recently purchased a new router since the old one fried during a power outage/surge. Now with the new router, I connected it to the modem and configured it with the default gateway, subnet mask, etc.

Our IP cameras are connected to the modem directly, and before replacing our router, we could connect to the cameras outside our network, and inside our network. But now we can only connect to them when we're outside the network, when we try to connect while inside the network we're met with an error. (when connected to wifi or ethernet to the router, we can't access the cameras)

All the guides and such always speak about IP cameras directly connected to the router, but for some reason, ours was connected to the modem this whole time (and it worked), but now it doesn't. What can I do to fix this?
Thank you!

Like many people, you are probably double-NATing, running on 2 subnets. Standard fix for your particular scenario: Configure WIFI router as Access Point.

Last time I tried to do that, I could no longer connect to wireless or wired internet, or even the router, my phone and other devices just kept saying "finding IP address" and then not connecting to the router. I had to reset the router to fix that. What should I do now?

I have no idea. I just know home networks are designed for a single subnet and if that doesn't work for you, you got something else going.

If you feel like posting a diagram, I may spend some minute to look at it.

Here's a diagram:

"internet" ---------------modem-------------router
(cable) ..............................|
.................................IP camera

Not enough.

You have to show me where your PC are, where your phones are... all relevant pieces you intent connected to this network.

Looks all normal to me. I have no idea why when you have a FLAT NETWORK, as suggested in #1, would give you any kind of trouble.

tmli :

Your modem is more than likely a modem/router combination (more than one LAN port and/or wifi capable?).

That would mean you're trying to access the camera from inside your network via 2 routers. It's 2 separate subnets unless you fix it as mentioned above (configure the second router as an access point).

It might be possible for you to access the cams by the private IP addresses assigned by the first router, but you will have other issues to fix in order for it to work right. The best method is to avoid this altogether and make 1 subnet.

That... actually makes sense! The modem has more than one ethernet port, but no wireless... But yeah, the last time I tried to switch the router to access point mode I was unable to connect to it at all- we have a static IP, would that have anything to do with the problem I was facing?

How do you connect to the cameras? Do you have a dvr? Do you browse to ip of the dvr or use a domain name?

tmli · Jan 8, 2017

nigelivey :

We have a DVR, and I think we just use the IP of the DVR (whatever our ISP assigned us, at least). We do not have a domain name.

as stated above follow the tutorial on turning your router into an AP.

It didn't work!
Actually, I ended up connected the IP cameras to my router, and opening a local port from the router, which then allowed me to access the cameras from both our home as well as our public ip address. Turning it into an AP didn't work at all, basically killed all Internet access every time and I had to reset it

What did you actually do to turn it into an AP?

tmli · Jan 10, 2017

nigelivey :

I went to my router settings, into wireless access point settings, turned it on and set up the static IP information. I tried it with both dynamic as well as static IP settings and the access point still did not work

Did you turn off dhcp, nat, firewall, set the gateway etc etc?

nigelivey :

Yep! So not sure what went wrong

nigelivey · Jan 10, 2017

Science is science, I don't know what you did wrong either.

I can't connect to IP cameras when I'm on the network, but I'm perfectly fine when not on the network.
