Title: Port Forwarding.....I'm so confuzzzzzed!
Post by: bbqbrisket on October 23, 2018, 12:41:41 PM
So all my port forwarding settings on my 880L are gone.  I am very confused with terminology.
When port forwarding for remote DVR viewing, do I have to enter in the following details:
1.  Port Forwarding and Virtual Server?
2.  Is port 8080 an example of an External Port? Is it also called a TCP Port (It's open)  (This is not my local Router Port)
3.  Is an Internal Port the same as a Mobile Port or something different?

Let's just start with this and I will be back for more.
Thanks for any help.

If you Port Forward, you need to disable uPnP as well ON the router.

You have ports that are internal and external and can be same port numbers or different.
Have you contacted the Mfr of your DVR for information regarding remote viewing with a router?

Ok...UPnP was enabled.  It is now disabled.  This may be a big help to start.

What are you trying to do? That will be easier to help you configure your router. Having UPnP enabled will eliminate the need to open ports for most applications.

Port Forwarding - Basically opens a port (or ports) to a specific device on your network. 

For example, you have an FTP server on your network. By default it uses port 21. You can open port 21 to the IP address of your ftp server. Any traffic from the Internet hitting your router on port 21 will get forwarded to your FTP server.

Virtual Server - Same as port forwarding but the incoming port (or ports) can be different than the port of the device on your network.

For example, if you have a FTP server on your network, you can keep port 21 on the server but some ISPs may block it so you can use say port 2121. In the virtual server setting, external port would be 2121 and internal port would be 21. This will tell the router any traffic coming in from the internet on port 2121 to forward to the IP address of the ftp server using port 21. Users on the Internet would have to specify port 2121 to gain access to your ftp server. URL = ftp://1.2.3.4:2121 for example.

External port = The port of the traffic from the Internet coming to your router.
Internal port = The port used by the device on your local network.

Trying to set up remote viewing on my DVR.
Initially, I can't see to get the incoming port open on 80.  It was at one time.  DVR is set up for 80.
Device or DVR is the "Mobile port" (Internal port)
Ok..UPnP is back enabled.
Also, when I put in my ip address from my PC (Whats my ip)...on Virtual Server, it changes to a different ip.
If you need any pics lmk
thanks for the help

If you are using the Xfinity app you shouldn't have to open any ports on the router since the DVR and the app communicate with xfinity, not the router directly. 

When testing are you turning off WiFi on your device and then launching the app?
Title: Re: Port Forwarding.....I'm so confuzzzzzed!
Post by: bbqbrisket on October 24, 2018, 10:08:39 AM
yes, wifi is off and data is activated.
I know of no xfinity app since it is not there security system that i am using.

What are you using to connect then if you are not using xfinity app?

Please explain EXACTLY what you are doing.

Ahh ok. You have xfinity by comcast and DVR so I assumed you were trying to view their DVR.  :P

In your DVR can you change the port? I would not use 80 or 8080 since those are default ports. Use something between 1024-65535. 8000 for example.

In the Meye app, enter a name, Address is the WAN/Internet IP address in the D-Link router, not the local IP.  Port = the port you entered in your DVR. Enter the DVR's username and password (if required).

In the router, go to Features > Port Forwarding. Click Add Rule. Enter a name, Local IP Address = the IP address of the DVR. TCP and UDP ports = the port you entered in your DVR and in the Meye app. Click Apply.

Test and hopefully that will work.

Ok...it appears getting more simpler as we talk.  I wll change those port settings on the DVR and router
so, to be clear, the WAN/Internet IP address in the D-Link router is like the default ip of my Dlink router like 192.168.0.1 for example;
So, do I have to enter the "Whatsmyip" address anywhere?
thnaks

My DVR has an http port, media port and mobile port enteries available.
Note, I have local access via Wifi with the DVR ip address and the "Media" port entered in the app.
Title: Re: Port Forwarding.....I'm so confuzzzzzed!
Post by: GreenBay42 on October 24, 2018, 12:54:35 PM
Try the media port in the router and see if that works. The app only has 1 port correct? Not sure how it communicates with the DVR. Try putting 8000, 8001, and 8002 in the 3 DVR ports and try each port in the app.

In the router, edit the same rule, enter 8000-8002 for TCP and UDP ports to open.

Oh I just caught something. You said the Internet/WAN IP on the dlink router is 192.168.x.x? Your modem is not bridged and this would explain why it is not working. The modem/router is most likely blocking the ports since it is double-NAT.

If you go to whatsmyip, that public IP address should be in the Internet IP address of the router (home page in the UI - click the Internet icon).

He has comcast with xfinity modem/router.

https://www.xfinity.com/support/articles/wireless-gateway-enable-disable-bridge-mode (https://www.xfinity.com/support/articles/wireless-gateway-enable-disable-bridge-mode)

Also according to meye app, the port used should be the mobile port in the DVR. The HTTP port and Media port (usually 554 for RTSP) may work locally but in the app remotely use the mobile port.

Modem is already "Bridged" so there is no confusion; the Dlink is being used.
Still a little confused though.
The ip address what I use to get into the router from my PC is the 192.168.......
The Whats my ip address considered the "public' address is the odd number of 73.226.173.....

so, I will put the "public" address into the meye and use the "mobile" port from the DVR.

Is it possible that it will not work when I;m in the house even though I have disconnected Wifi and enabled "Data" on my cell?

Yes you have to use the 73.xx.xx.xx IP to use the app remotely.

It should work if you turn OFF Wi-Fi and use 3g/4g as long as the public IP is in the app and the ports are opened in the D-Link router.

When you log into the dlink router, is the Internet IP address the 73.xx.xx.xx IP address?

When I log into my router, I use the 192.168...... but this is only for wifi in my house on either a pc or cell.
I cannot log in to the router using 3g/4g with either the router log in 192.168 or local ip 73.226... (now that I understand, thanks to you guys), what a "local ip" is.
when i check port opening, it says that port is "open"

Post by: bbqbrisket on November 02, 2018, 07:09:55 AM
Well, yes and no.
I can now log in but I found out that once I changed the port settings from 80 to something else, I now have to include the port at the end of the ip address.  It seems by default all the devices are set at 80 so I don;t need to implement the port number if it;s set to 80.
So, one issue is that I don't know how to change the default port on any device or pc to something other than 80.
I am still unable to log in remotly using the public ip address.
I need to thank all who contributed to this so far as now I understand the definition of various terms that also seem to have multiple terms that mean the same thing.  The example for one is "opening a port" equals to "port forwarding" or "what'smyip" is the equivelant to the "public ip address"
