No Internet Access to ISY after dynamic IP change

[bjackson]

Hi,

I have an ISY-99i with v2.7.0 firmware and a DSL modem running in "bridge" mode to a Linksys WRT-54G WiFi router.

 

I also have a Panasonic network camera, model BB-HCM511A, which includes a DDNS service. The DDNS URL for the net cam is http://xyz.viewnetcam.com, where 'xyz' is unique to my DDNS account. The cool thing is the Panasonic Network Camera has an internal DDNS agent so I don't have to have rely on having my desktop PC running a DDNS agent to catch IP address changes.

 

The issue I'm having is anytime my Internet Service Provider (ISP) assigns a new dynamic IP address to the DSL modem, I can't access the ISY-99i from the Internet unless I recycle power on the ISY-99i.

 

Here's the sequence:

1. ISY-99i is powered on.

2. Able to access the ISY-99i via https://xyz.viewnetcam.com:443 from

the Internet.

3. ... days or weeks go by ...

4. My DSL modem dynamic IP address changes.

5. I can access the Panasonic network camera via

http://xyz.viewnetcam.com from the Internet with no problem.

6. However, I cannot access the ISY-99i via https://xyz.viewnetcam.com:443

7. Cycle power to the ISY-99i.

8. Now I can access the ISY-99i via https://xyz.viewnetcam.com:443

 

Would assigning static IP address to the ISY and explicit port 443 forwarding fix the problem - guessing this could be UPnP issue?

 

Thanks

Bob

That's what I would suggest.

 

Also, any reason why you're not using your router for DDNS updating?

I too utilize ISY and Panasonic cameras. You need to re-configure your camera to non-veiwcam mode. Go back into your setup and remove the config's for any access from the internet. Do not use the veiwcam option. Next set your camera up for a static IP address, use that address in the setup section of the cam. Now go into your Linksys router and set the camera up as TCP and port forward a port of your choice (anything other than ISYs 443). Now go to the DYNDNS.com webpage and set up a dynamic dns account (it's free). Select an easy to remember name for your new dyndns URL. After the account is setup, configure it with a password and username. Go back to the Linksys and apply the option for Dynamic DNS, it will ask for the username and password. Then when your ISP changes your IP, the modem will automaticly send out a "change of address card" to DYNDNS. They claim as long as a half hour to complete, but my history is zero wait time. When you surf to your DYNDNS URL, DYNDNS will redirect you to your cam/ISY network. Your configuration will require a port number for the cam but simply going to your DYNDNS address will go directly to your ISY (port 443). I know it sounds complicated but it works flawless. My old ISP tried talking me into "business class" for $50 amonth more and said there was no way around it. This is a free way around it. PM me if you'd like me to walk you through it. I'd be happy to pay back some of the help on this others have given me.

Appreciate for the reply.

 

I left the Panasonic netcam configuration "as is" and went with a DynDNS account, static IP and port forwarding. Internet access has been reliable now for almost 2 weeks. I posted the tutorial at
