Question

Home Networking and Outside World

Jul 14, 2017 1:02PM PDT

Hello everyone,

I'm trying to get a handle on my home network and be able to access my home network from the outside world. I will give you a quick rundown of my setup for more info.

We receive our internet from a provider that beams their signals from what look like cell phone towers directly to a small dish on the side of my house. I can see the tower about a 1/2 mile away. There is a network cable that runs from that dish into my media closet that has an IT rack with equipment on it. The network cable from the dish goes into a little black box (the size of a power supply box for a laptop) and another network cable leaves that box and goes to my router. The only other plug on the box is for power.

When I go to google and type WhatsMyIPAddress I get an address that starts with 50.xx. When I go into my router settings it says my internet address is 10.xx and all of the devices on my network are 10.xx. When I go to the 50.xx ip address in a web browser it brings me to a Mikrotik Router login page where admin is already populated in the username and of course I don't know the password.

Does this sound right or normal or am I missing something? From everything I've read, if my public IP address and WAN/Internet IP address do not match than I'm in a Double NAT situation.

Public IP vs Internal DHCP assigned IP
Jul 14, 2017 1:11PM PDT

All seems well to me about it. Your ISP assigns and IP address to your location, but that ends for your computers and anything using the router since it then assigns using DHCP internal IP addresses to each device it serves.

Why the difference
Jul 14, 2017 1:14PM PDT

Makes sense but then I would think the Internet Address on my router would match the 50.xx assigned by my ISP right? I know the router assigns IP addresses to all the devices behind the router but what assigned the router the IP address of 10.xx?

the router assigned that address to itself

If you wanted the outside IP address go direct to your computer, bypassing all the protections it offers, then you can set the DMZ and point it to your computer. That's dangerous though.

The essence of a Routing Table
Jul 22, 2017 6:17AM PDT

In your case Websites like Google, You tube etc use 50.xx since this is your public ip address, also known as the global address. Routers are designed mainly for LANS/WANS so its been configured to assign 10. xx on your LAN . All Routers have a routing table, where it dynamically adds ip addresses so a difference in ip addresses will not cause an issue.

Sounds like a WISP to me.

It's a typical problem and you tell the client that is way out on a limb. Some take this as an affront but it is what it is.

https://www.google.com/search?q=vpn+into+a+wisp+double+nat+server confirms this is a well trodden beat up issue but to solve it, you need to get something reachable on the LAN.

In short, wrong internet system for folk that want to remote into their home LAN.

Good Article...

I read the first link that popped up and the posts related to it. My ISP does have on their website that remote camera viewing or smart home applications will require additional equipment and a public ip address. I'm guessing that's my problem and it's a way for them to make more money if you need to be able to get into your home network from the outside world.

So can we focus on a specific thing?

If one wanted to say get to a camera at the home there may be systems that push pictures or video up to the cloud where we can check in. Or email me when there is activity with a picture.
