Unable to connect to IP Cameras from Outside the Network

Unable to connect to IP Cameras from Outside the Network

Need some assistance. I have IP cameras as well as Home automation Switches, etc... throughout my home.

From inside my WI-FI network, I'm able to access, view and control all devices, but from outside the network I have connectivity issues.

I mostly try to connect from my Cell Phone and Cellular enabled iPAD.
In reviewing my logs, I believe I've found the culprit, but do not know how to clear it.

I receive the following constantly:
[DoS attack: Vanilla] attack packets in last 20 sec from ip [70.194.129.243], Saturday, Apr 11,2015 07:59:58

The IP address listed appears to belong to my cellular provider, Verizon Wireless.

Why is my router seeing an incoming request for connection as a DoS attack?

Looking for any assistance, all would be appreciated.

I had the same problem with one of my viewers I was using on my iPhone. Other viewers worked fine.
I solved my problem by setting all the cameras on the same internal port.

Re: Unable to connect to IP Cameras from Outside the Network

You need to portforward the IP camera and open a port.
So if your IO camera has an IP address of 192.168.1.21:8001
You need to portforward the 8001 port.
Secondly, you need a DYNDNS service.
I use DYNDNS.org

Cyber99, I do all.... Each camera has unique port: 25006, 25007, 25008, etc.. I set up port forwarding using the same internal and external port. I use Dyndns.org with DYNDNS PRO with Health check. When connected via Wi-Fi at a remote site, the issue seems to go away. As indicated, based on the log files, the incoming connection from Verizon Wireless is getting blocked as a Denial of Service attack.

JimLS, I've tried a few, same results. As indicated, the problem appears to be at the router. The log file shows incoming connection attempt from Verizon as a DoS attack and blocking the request. In almost all cases, when connecting using Wi-Fi at a remote location I'm able to connect.

Did you try setting all the cameras on the same internal port?

I use Vrison wireless LTE service and Roadrunner (Time Warner)
Do you access your port using the dyndns service on your phone?
When I set up my iPhone app I use the dyndns address.
If the port is open you should have access.
I don't think it's a router issue.
Do you have your DNS service setup on your router?
Do you have your UPnP turned on in the router setup?
Is the address on your phone correct with the correct password?
Just a few suggestions where I have messed up in the past and went crazy looking for an answer...finding out my address on my phone was wrong.

Cyber99,

Do you access your port using the dyndns service on your phone?
* I do, all apps are set up to point to lastname.dynds.org:port #
If the port is open you should have access.
* I do, from all but Verizon Wireless
I don't think it's a router issue.
* I would respectfully disagree. The router logs clearly indicate that the incoming signal from the Verizon IP address is being blocked as a DoS attack.
Do you have your DNS service setup on your router?
* I do, but to be honest, am not sure how this factors in. Correct me if I'm wrong, but DNS is for outgoing address resolution and should not affect incoming connections.
Do you have your UPnP turned on in the router setup?
* I have tried both, no changes in the symptoms.
Is the address on your phone correct with the correct password?
* It is. I can access all devices internally with no problems. I can access externally from public WI-FI network. The problem seems to be specifically with incoming signals from the Verizon cellular network.

Perhaps I should have prefaced my request with my background - I've been working in the IT industry since the early 90's. While I'm not a Network Engineer, I'm comfortable navigating my way around network issues. I provide IT and connectivity support for the Department of Defense, providing IT services for approximately 10K military and civilian personnel.

I have checked and re-checked the obvious and am comfortable that the problem is either with the Firewall of the router, my configuration at DynDNS, or with the way Verizon communicates with my system.

I appreciate all input provided so far and look forward to more ideas.

Re: Unable to connect to IP Cameras from Outside the Network

Makes no sense.
What phone you using and what app?
I use the Surveillance Pro app on an iPhone.
It might be an app problem.
Just another possible problem
I been networking too for quite a while since 1993.
I'm not a trained expert but been thru it all.
