Port Forwarding Issue

Seems the installers know very little, or are told to do very little, of the network side of the install. One of the few reasons I don't suggest Cox Home security to my friends. 

Sounds like what you have is a dual NAT situation. A easy solution would to go Modem > Cox router > your router and then put your router in Cox's router DMZ. Thats not a perfect solution and is a security vulnerability so..

1. What are the model numbers of the two routers you have? Also what kind of modem?

2. What do you need port forwarding for? Which ports? If you want to keep the port numbers private, just give me the purpose and label it  letter, like port A.

3. Besides the Cox router, did they install anything else  like a PVR or IP cameras?

The technician set up the cable modem connected to the cox WNR1000 netgear router WAN port. The cox router LAN port 4 is connected to my Cisco EA6500 WAN port.

I don't have access to the netgear router configuration so I can't change any settings. They have wireless control panel and sensors tied to netgear router. No PVR or IP cameras from Cox.

I have my own FOSCAM FI8921W cameras. I set up port forwarding on my Cisco EA6500 router but can't see them from the internet via the netgear to cisco connection. 

The modem is a motorola surfboard 5101.

So to confirm SB5101 > WNR1000 LAN > EA6500 WAN > Computers

If you have no access to the WNR1000 then that makes this difficult. The best solution would be to find some way to get the EA6500 to work with the Home security. Then there is only one device which is better for performance and simplicity reasons. That would require them telling you what services need to be allowed, or which ports forwarded for the security system to work. I would suggest discussing that off a public forum.

The next best thing would be to have Cox give you access to the WNR1000. If that's a impossibility, then move on.

The third option is to go SB5101 > EA6500 LAN > WNR1000 LAN. Then go into the EA6500 and find out which IP the EA6500 is giving the WNR1000 and assign a DHCP reservation for that address(See page 31 of link below). Then put that IP address in the EA6500's DMZ (See page 41-42). 

Linksys EA6500 Manual.

The last option is the way they should do if they wanted to do it right, and thats include a 2nd IP if you bundle Home Security with Cox Internet. Then you could go SB5101 > Switch > Both EA6500 and WNR1000. This wouldn't require any configuration change of either router, so it's the simplest way to fix the issue, but as of right now it cost money for a second IP, AKA Multiple Computer Access. 

Hi, Internet Wifi.
Its recommended that the home security router always be directly connected to your modem. Access to the device's settings is restricted to protect the nature of the product. Your security system wouldn't be doing you much good if it became susceptible to outside access. As for your port forwarding issue, first make sure the connections are:
Modem>Security Router>Personal Router
Then what you'll want to do is (via the touch panel) access settings/advanced settings/connectivity/ and select "expose personal router to internet."
Hope this helps!

Colleen,

The problem with that solution is he has security cameras connected to his router which you are suggesting he place second, after the Cox router. That breaks the port forwarding chain he has programmed into his router for his cameras. Since Cox isn't configuring their routers correctly for the install, and since Cox won't let him change the settings on the router (IE DMZ, port forwarding, etc) is not the only solution to place his router first? Also, wouldn't having a totally separate IP and a totally separate firewall be more secure? I think home security would be a good first place to try out IPv6 for even added security.
