Hi, I am installing a wireless...
Hi,
I am installing a wireless IP Camera Tenvis JPT3815W.
My wireless router is a Netopia 3347W
The OS is Windows 7
I am reasonable competent re configuring the system and have conected the camera via wireless and set up the DDNS. They both work fine as does the camera image with the plugin installed in IE.
My problem is Port Forwarding. I have configured it using the excellent guide on the Port Forward web site.No problem there. I used their port checker but whilst Iwas accessing the router the port (85) was not locatable or opening.I turned off the firewall in the router but still it did not work.
I then disabled security in the PC but that did not help. Switched it on again and I could not even access the router via the port checker never mind open or find the port. Must confess I am a bit confused by security in Windows 7
Pinging the router worked fine.
So as I see it there are two problems
1 Sorting the security in Windows 7
2 I am fairly sure I set up Port Forwarding in the router but it don seem to work ??
3 I would really like help from someone familiar with the Netopia 3347W as I have found it difficult in the past
Thank you for your interest and i hope you can help

RichieMe :

Hi there and welcome

RichieMe :

the port open sites dont always work correctly

RichieMe :

I would not worry about that too much, but test if you can see the camera

RichieMe :

can you test this please?

Customer:

Hi, Richard'

RichieMe :

Hi

Customer:

Yes the camera is working as already stated as is the DDns.

RichieMe :

sorry I missed that

Customer:

The port checker was at least detecting the router but when I messed with the security it would not work but it did ping as already stated

RichieMe :

ok, if the camera is working, port forwarding it working

RichieMe :

The camera would not work otherwise

RichieMe :

as the router would not know where to push the external requests to

Customer:

No because I am accessing it on the local network rather than outside the router

RichieMe :

ok, sorry you said it works

RichieMe :

do you want me to test here if it is working?

Customer:

The camera was working even before I set up port forwarding in the router

RichieMe :

it will always work on the LAN

RichieMe :

port forwarding is to allow access from the internet

Customer:

Yes it would be a great idea for you to test if it is working the port is 85

RichieMe :

ok, and the IP Address (public)?

RichieMe :

\

Customer:

sri for delay 109.76.51.166:85

RichieMe :

no problem

RichieMe :

let me check it

RichieMe :

can you go to

RichieMe :

make sure thats the correct IP as I get no activity there on anything (not ports, but the IP)

Customer:

yuo could also try laurelsecurity.dyndns.org:85

RichieMe :

trying now

Customer:

yes that is my IP just checked it with whatsmyip

RichieMe :

ok, why did you pick 85 as the port?

RichieMe :

it is reserved and can cause problems

RichieMe :

can you use 11001

RichieMe :

this is dynamic an private (meaning for personal use)

Customer:

Tenvis suggested it and port 80 was used by a web server

RichieMe :

do you have a web server running there?

Customer:

had but not now

RichieMe :


ok, I get no activity on this IP









What ISP modem do you have?




 

Customer:

Not sure what u mean the modem is Netopia 3347W and my isp is vodafone

RichieMe :

the Netopia cam from your ISP?

RichieMe :

came*

RichieMe :

Can you tell me how you did the port forwarding (the values used)

RichieMe :

and if for TCP and UDP?

Customer:

85 and TCPip

RichieMe :

ok, forward on UDP as well please

RichieMe :

you will see this in the protocol list

Customer:

Yes but what port for UDP

RichieMe :

also 85

Customer:

both on 85

RichieMe :

yes please

RichieMe :

we are going to forward both the protocols on port 85 to the camera

RichieMe :

did you specify the correct IP of the camera?

RichieMe :

as the destination?

Customer:

Yes

RichieMe :

done?

Customer:

Yes I have config utp and tcpip to port 85 for camera ip

RichieMe :

ok, let me test

RichieMe :

ok, still nothing

RichieMe :

let me check something

RichieMe :

ok, I think Vodaphone is blocking this

RichieMe :

the webserver

RichieMe :

you ran that from hom?

RichieMe :

home*

Customer:

Yes

RichieMe :

ok, are you 100% sure the correct IPm to the camera is used for the port forwarding?

Customer:

Oh if you were talking about the old web server that was some time ago and with a different ISP

RichieMe :

ah ok

RichieMe :

can you view the camera over the web page? or you need an app?

Customer:

Using IE8 and a plugin called VLC

RichieMe :

getting the manual now

RichieMe :

i min, let me check the camera

RichieMe :

ok downloading, will take a while

RichieMe :

I think either the IP is wrong or Vodafone is blocking (which they do)

RichieMe :

where did you get the IP for the camera from?

Customer:

You can config the if of the camera but I left is as supplied.

RichieMe :

configure it please

RichieMe :

to make sure you have the right IP set

Customer:

Hi I am trying to send u the images as attachments of all the configurations but I can seem to paste them

Customer:

They will reassure that those settings are correct

RichieMe :

you see the paperclip?

Customer:

yup

RichieMe :

click on that

RichieMe :

then the blue table thing

RichieMe :

to upload

Customer:

yes

RichieMe :

ok, upload it please

RichieMe :

and then I can view it

Customer:

Hi,

Customer:

u got that

Customer:

??

RichieMe :

no i didnt sorry

RichieMe :

upload to www.wikisend.com

RichieMe :

and send me the download link please

Customer:

Try this pse

Customer:

Could it be anything to do with firewalls?

RichieMe :

are there two cameras or 1?

Customer:

1

RichieMe :

no as we port forward through the firewall

RichieMe :

I see the server is the same IP Address?

RichieMe :

let me check the camera manual please

RichieMe :

ok, the server thats specified

RichieMe :

what is that?

RichieMe :

as it has the same IP

Customer:

the only way I could allocate the UPt andTCPIP was to deal with it twice but as you will notice both have the same IP address

RichieMe :

ok, this can be the problem

RichieMe :

give one of them a different IP

RichieMe :

and make another port forward on port 86 to the second ip

Customer:

I think there is a problem as the IPs are derived from the availabel devices henceI just cant create an IP/

Customer:

There is only one camera

RichieMe :

you can assign an ip to it

Customer:

Do u want me to change the IP of the camera and if so to what? and then allocate to port 86?

RichieMe :

1 minute, I need to check something

RichieMe :

why the server has the same IP

RichieMe :

and if this is normal

Customer:

AS I understand it the camera is acting as a camera server with an IP address which I would imagine is notmal

RichieMe :

this is what I am double checking

RichieMe :

ok, yes, the server is built in

RichieMe :

but

RichieMe :

you have http port as 81

RichieMe :

not 85

RichieMe :

thats a problem

RichieMe :

it needs to be the same port the port forwarding happens on

Customer:

OK let me change the camera port forwarding to 81. U OK with that??

RichieMe :

yes

Customer:

Just a min

RichieMe :

thanks

Customer:

OK Thats TCP on 81

Customer:

OK?

RichieMe :

let me check

RichieMe :

ok, nothing

RichieMe :

and we know now that the settings are correct as the port was 81

RichieMe :

the issue is

RichieMe :

I dont get any response to the IP at all

RichieMe :

this means that Vodafone are blocking external access. Some ISP's do this

RichieMe :

and I believe this is your case

RichieMe :

there is no way to get around this sorry

Customer:

Maybe

RichieMe :

if the settings are now correct, which it is with the port

RichieMe :

then this is the only reason

RichieMe :

as we know the cameras work

RichieMe :

and you port forward 81 to the ip of the camera correct?

Customer:

Perhaps u could advise on what I did with my security on windows 7 that is blocking the port checking. It was working till I i switched it off and on again

Customer:

To your question

RichieMe :

Firewall. Is the camera running via the computer?

RichieMe :


  1. Open Windows Firewall by clicking the Start button Picture of the Start button, clicking Control Panel, clicking Security, and then clicking Windows Firewall.




  2. Click Turn Windows Firewall on or off. Administrator permission required If you are prompted for an administrator password XXXXX confirmation, type the password XXXXX provide confirmation.




  3. Click Off (not recommended), and then click OK.




 

Customer:

The http portfor the camera is 81 and I have set the port forwarding also to 81. That is what u mean?

RichieMe :

correct

RichieMe :

that is the right setting

RichieMe :

but the camera goes via wireless right? as it should

RichieMe :

not via the computer?

Customer:

Yes

RichieMe :

ok, then it is a vodafone block

RichieMe :

as I said, some ISP's do this

RichieMe :

and everything is setup

RichieMe :

this is the only reason left

RichieMe :

as you know they work via the LAN

Customer:

I really think think we are stuck at the mo

RichieMe :

we are

Customer:

Where are u located as I think it is time to call it a day

RichieMe :

Australia, but 1 minute

RichieMe :

I am looking at Vodafone Ireland Terms and Conditions

RichieMe :

to see mention of this

Customer:

Maybe you could think about it and finalise it later.

RichieMe :

the dont mention this (not always they do)

RichieMe :

but ehre are people with other problems

RichieMe :

due to blocked ports

RichieMe :

but you are stuck here

RichieMe :

we cant get around it other then switch ISP

Customer:

Can I check port opening from within the router eg ping 192.168.1.239:81 just to confirm that port forwarding is ok . or must it be external to the router

RichieMe :

external, but I am checking that :)

RichieMe :

have been the whole time we test

RichieMe :

and I get nothing on no ports

RichieMe :

thats why I say its vodafone

RichieMe :

I see this from time to time

RichieMe :

with my customers

RichieMe :

mainly when they try to do webserver from home

Customer:

I know that but I want to try to continue testing from my own site and of course it therefore has to be within the router

RichieMe :

you can when you go to work?

RichieMe :

or a friend can?

RichieMe :

but there is nothing you can do :)

RichieMe :

port forward

RichieMe :

thats it, you only need to do that

Customer:

OK

Customer:

Thank you

RichieMe :

your welcome

RichieMe :

think about changin IP's if you need the cameras from outside

Customer:

OK Richie We will call it a day

Customer:

Again

Customer:

Thank you

RichieMe :

have a nice sleep!

RichieMe :

and all the best
