IP Camera, can't view from external web

I have read the posts but must be missing something with my xfinity router.  My IP camera (ethernet cable to router) works fine from my wireless computers but I can not access it from the web externally (when I am off at work or using my aircard instead of my wireless network).  Here are my settings.  Any help would be appreciated.  I set my router firewall on the custom, lowest settings (I think).

 

Router
10.0.0.2  -IP
255.255.255.0  -Subnet
10.0.0.1 -Gateway
75.75.76.76 -DNS
75.75.75.75 -DNS2

 

Camera
10.0.0.178  -IP
255.255.255.0  -Subnet
10.0.0.2  -Gateway 
10.0.0.2  -DNS1
200  -Http port

 

Port Forwarding
-Enabled
http  -Service Name
TCP/UDP  -Type
200 -Start Port
200 -End Port
10.0.0.2 -Server
Active

 

Internal network (wireless) Camera address
10.0.0.178:200  -(working fine)

 

External camera IPs  -(Not working when viewing elsewhere)
http://98.198.56.191:200/

Re: IP Camera, can't view from external web

Your port forwarding setup is incorrect, the target server IP address needs to be the IP address of the camera, not the IP address of the router.  So change that to 10.0.0.178.  Also bear in mind that many routers do not allow a connection to the router's WAN IP from BEHIND the router, so make sure you test this from an external system.

Re: IP Camera, can't view from external web

I switched IP as below, thank you

 

Port Forwarding
Enabled
http  Service Name
TCP/UDP  Type
200 Start Port
200 End Port
10.0.0.178 Server
Active

 

Unchanged on external test, unable to connect in.  I can still connect to IP camera locally through wireless.   (Using Tetherbridge from my Blackberry to test the external connection). From external I am using  http://98.198.56.191:200/   and browser just hangs up. Is it a router or comcast Firewall? Do I really have external access to my own IP through comcast?  What else?   Thanks for any avenues, I just dont have a clue what to do next.

Re: IP Camera, can't view from external web

Comcast is NOT blocking you, either the router is setup improperly or has some other issue, the IP camera is not accepting external connections for some reason, or there is something wrong with whatever browser you are using.  I'm not familar with Tetherbridge on the Blackberry so I can't comment there.  Make sure you reboot the router/gateway after making any changes.  I do know that lots of folks have complained about port forwarding not working correctly whern they are using one of the Xfinity Wireless Gateways (which are junk).  So if you have one of those (and your router IP address suggests maybe you do), I recommend having it placed into bridge mode by the good folks at 800-363-2416 and get a decent router, or just call the support folks at that same number and ask them what's up.

Re: IP Camera, can't view from external web

Okay thanks.  Wasn't rebooting router, will do that.  Yes have a Xfinity router, sounds like the bridge mode (pass through?)  is in order and will call them.  Tetherbridge is just a way to use Blackberry as pc modem (it is quite good backup internet connection and very cheap one time charge, I think it is legal anyway)  I highly recommend it.  I don't understand how it is I can get all this free help from you, but please tell me who else to thank besides my gratitude to you.  Much thanks I will keep plugging and post if I ever get this solved.

Re: IP Camera, can't view from external web

SUCCESS.  I can now view camera externally!  I did what you suggested and had Comcast bridge the Xfinity modem/router (so it is only a modem now and I use my own personal router) and also changed my camera gateway back the way I had it initially because my camera manual suggested that.   My personal router does not use port forwarding but calls it a virtual server instead.  It also automatically mirrors the virtual server settings to the router's firewall, so I did not have to adjust the router firewall myself.  Comcast confirmed the port forwarding is a problem with their Xfinity routers.  Thank you again.  I hope this thread and your advice helps others.

Re: IP Camera, can't view from external web

Glad you got it working.  Yes, the terminology for port forwarding varies from one maker to another.  "Port forwarding" is by far the most common term and it describes what is being done, but some makers like to change things in a quest to increase "user friendliness".  I'm much more a fan of standard terminology than whatever some maker thinks is more "user friendly".  Just my opinion, though.
