Home Networking / Router / & WiFi Gateway Help

I'm trying to remotely connect to an IP camera. I have port forwarded the router and I can do this with no problem on my LAN but when trying to come in through the Internet, no connection. Appears it's being blocked by the modem. What's the procedure for punching through the modem?

There is no procedure for punching through the modem because it's not blocking you, and even if it were there is nothing you can do about the standard blocks that are in place.  Unless you are using one of the ports that Comcast blocks (in which case you are misconfigured), the problem lies elsewhere.  It's hard to help here since you provide no concrete information.  What modem?  What router?  What is the exact port forwarding configuration you are using?  What IP camera?  How is the camera setup?  How are you accessing the camera, both from your LAN and from outside?  Many routers do NOT support a connection from the LAN to the router's WAN side and back into the LAN again, for this kind of testing use a real external system.

Sorry about the delay in replying. My ultra-reliable Comcast cable was out for 5 days. That's another rant I'll save for another day.

Camera problem: The Comcast modem is a Mororola SB5101U. The router is Netgear WNR1000. I'm using port 1180. The camera is a DB Power, made for Internet monitoring. Setup is accomplished via a network cable.

After setup and going to IP, I can see the picture fine on my desktop. I can access it from my laptop via the wireless LAN. However, when I try to access my IP from another Internet point using the address format 192.xxx.x.xxx:1180, I cannot connect. I can't even connect without using the port. However, I can use Team Viewer and access my computer just fine.

Any further suggestions?

Thanks and regards,

192.168.x.x addresses are private, they can only be accessed from the LAN. When you want to access it remotely, you have to use your PUBLIC address, not the private one.

Since this address can change, you should use a dynamic DNS service to assign a name to your address. Sign up with a site like dyndns.org, and then go to the Dynamic DNS page of the router's configuration to have it automatically update the service.

I am using the new Arris Gateway from Comcast and have everything functioning but my IP Camera.  My camera works fine local (10.0.0.3) but I can not find the correct IP to use for the network.  I thought it would be on the gateway configuration utility (10.0.0.1) under status but the IP i find their doesn't work remotely or at least not consistently.  I am kind of guessing on the port (80) and one time I did see the camera functioning when I was on a public wifi, but certainly haven't figured it out to where it is consistent.  Any help please!  I have contacted comcast consistently but they only seem interested in selling subscriptions.

What is the exact model number of the gateway?

There are manay, many threads in these forums about those gateways, and problems in a number of the functions they are 'supposed' to provide, port forwarding among them. You have a couple of possible options, should you so choose.

The primary option, most favored by folks here, is to get your own router, then use this number during regular weekday business hours to reach the NASR dept / techs; 1-800-363-2416. Ask them to place the modem in Bridge Mode. Connect your router to it, and do all your port forwarding there. You may want to forward a differnet port than 80 to your camera though.

Be advised that we have been seeing posts here lately indicating long wait times at that number. If you can't get through, try sending a private forum message to one these employees;

The other option is to go to this page, and use the link there to have your gateway replaced with a differnt model.
