ip address ping issues

[jonnyc925]

My computer can access the Internet with no issues . I can also remotely connect to the computer with logmein. My problem is that when I try to ping the Ip of the computer I get a fail. How can that be?

 

[Fardringle]

Many internet routers and devices block or ignore ICMP (ping) requests.

 

[QuietDad]

One of two reason off the top of my mind. Your Modem or router is set to block ICMP requests OR your behind a router and pinging the ip address the router is giving you and not the IP address of the router

I guess I should clarify that I a trying to ping the modems external v4 ip address. Isp is AT&T. Motorola nvg510 modem/router. I can't find anything about pinging being blocked either.

 

[Fardringle]

Is there a particular reason why you need to ping your own public IP address? If the connection works, and you are able to connect remotely to your home machine, does it matter? The ping command only tests the time it takes a remote machine to respond, if it responds at all. It's not really useful for much other than that unless you are pinging a server that is known to respond to ICMP requests (like www.google.com for example) to check your own connectivity.

I have a security camera system that is unable to be viewd remotely because the ip address is unreachable.

You likely have to open up a port on your router and forward it to the IP camera(s), which port though will vary from manufacturer to manufacturer.

Port numbers

 

[jonnyc925]

Port 35000 forwarding is already set up. Scanning the port fails though because the ip cannot be reached

On a real router (not home) if you set up things like IP devices you have to set up an exclusion list if you want to hit them by their WAN addresses locally.

I'm pretty sure that the reason the remote access to the cameras isnt working is ecause I can't ping the address. I think it is an issue with at&t but I'm not sure how to get them to fix it...

What router and what's the setup? Not everything answers to pings.

What router and what's the setup? Not everything answers to pings.

And what cable/DSL modem do you have as well? Some act as modem AND router so you will need to forward the port there as well as on your separate router (if you have one).

 

[jonnyc925]

The setup is a standard AT&T uverse broadband connection. Motorola NVG510 modem/router. I have the same setup at my house and several relatives houses. At every other service I am able to ping the external ip of the modem/router with no timeout issue. the address im trying to ping is 162.238.84.47.

@jonnyc925: were you able to solve your issue with Uverse Motorola NVG510 modem/router not allowing external access to your security camera? Please, I am having similar issue and will surely the glad to get some help. Thanks

Assuming that there is only the ATT Modem/Router and no secondary local Wireless Router.

As an Example - Assuming that the local IP of the camera is 192.168.1.1 and port 59999 is chosen as its port in the camera's configuration menu. Open port 59999 in the Router pointing toward the camera's IP.

From internal computer on the LAN the camera should be reached by a Browser putting 192.168.1.1:59999 as an address (check it to make sure that it is working locally).

Assuming that the external ATT ip is 107.77.75.xxx and that port 59999 is opened in the Router toward IP 192.168.1.1

The camera should be accessed from any place in the world by putting into a Browser - 107.77.75.xxx:59999

If your External IP is not static, open an account with DYNDNS.org or NoIP.com

Choose a subdomain and set your Router to use the account.

Example - if you established jonnyc925.DYNDNS.org as your subdomain the Camera should be viewed at -

jonnyc925.DYNDNS.org:59999

No local IP can Not be use for outside viewing the Routing is done via Open port.

P.S., please note that in order to be sure that it is working you need to first make sure that local IP works locally and then to try it from an other location. Trying to use the external access from inside your own Network in many case does not work.
