Cant open port? or use port forward

Hi,
I have 4 computers at home. One of them having DVR card to record camera activities. The great US Robotics router is used to connect the internet and rout home network.
I have configured the router to connect the net.
Then configured the wireless security.

Router IP: 192.168.1.1
Subnet Mask: 255.255.255.0
IP Range: 192.168.1.2 To 254

My PC: Vista (192.168.1.2)
DVB PC: I installed and configured the Digital Video recorder on (192.168.3)
DVR Software is: ShareBit and DVR ports are:
Net Trans Port: 5191
Web Server Port: 80
FTP Server Port: 21

ShareBit has Server and Client software. I installed Server on 192.168.1.3
And installed client on my PC 192.168.1.2
Both working fine
On my PC, when I go to IE and write the address 192.168.1.3; I can access and view all cameras.  So, Client software and IE plug-ins are good on LAN.

Then I went to my nieber's PC and installed client software (just to share the outdoor camera). Software is working perfectly.
But when I tried to access the camera using IP address. It did not work.
I came back home and setup no-ip.com (dynDNS) as: cam.biguae.com and DMZ my router traffic to 192.168.1.3 (which is DVR server).
When I try to access the camera by hostname. It is redirecting me the router page. However, by local IP address is fine (192.168.1.3).
I then did then tried to use the virtual servers options but gave me same result (It is redirecting me the router page).
Then tried the IP Filtering  Inbound Filters to redirect traffics to the DVR server but it gave me same result (It is redirecting me the router page).
I went back to my nieber's PC and tried it using hostname. It did not detect or route anything at all. It just says page not found. Even when I use the port number after the hostname.
Note: I also opened the ports in server pc using network connection firewall.

Any idea what is the problem??

1./ It's go to your router homepage because you allow remote management to router on port 80, so It did not forward traffic to port 80 to your local server. So turn of your HTTP remote management port on your router or change it port from 80 to another one port.

2./ Dont use your local IP as DMZ. It's very dangerous. just use virtual server instead

Thanks for your recommendation. I've disabled DMZ and using VS now.

I checked my router for remote managmen but found this:
Simple Network Management Protocol (SNMP) = Disabled

There is no remote management other than that.

BTW: when I configured the router traffic of port 80 to go to 192.168.1.3, it says "Since port 80 is used, the router WEB server port will be moved to 8080" that router now using port 8080. But i can see on the address it did not change to 8080??!
"when I configured the router traffic of port 80 to go to 192.168.1.3, it says "Since port 80 is used, the router WEB server port will be moved to 8080" that router now using port 8080. But i can see on the address it did not change to 8080??!"

This mean what I said above. The router change itself http port to 8080 and let traffic to port 80 go through to 192.168.1.3.

Can you tell me model of your router, I'll post some pics for you for more details. And another test, after apply VS port 80 -> .1.3, you go to http://your-router-internal-address:8080/ and see it display the router web interface?

Hi bujumah,

So can you go to http://192.168.1.1:8080?
And can you access your DVR Camera from outside?

Can you post your Virtual Server Page here?

Sorry,
http://192.168.1.1:8080 is giving me
Internet Explorer cannot display the web page

And http://192.168.1.1 is still the router page

So, there is no change!!



Did you reboot from last configure. Because in the usr support site, I also did not find anythign about changing the Web GUI port from 80 to another port (I tried the demo interface of your router and it has nothing about changing port). But as the alert you said above, USR router automatically change his GUI port from 80 to 8080.

So please try reboot your router and upgrade new firmware (I saw your firmware a litle old). See here:

Yes in fact I did restarted the router.

I tried to upgrade to the newest firmware but it says there is no upgrades available on the router page. But on their website; yes there is newer one.

OK dear. I will upgrade and start over fresh.

Will update you. Thanks.

Hi,
Upgraded the firmware to 26-06-2008.
Same thing. Router port did not change although they said its moved to port 8080

I need to access this through web to be able to see it form work and our domain admin wil not allow installing client software on my pc :(

BTW: I tried same thing with Linksys. Just the same story happened. I'm not sure of the main reason.

I'm not sure of the module but I just took it from my brother for testing and he took it away.
So try the test above and give me the result.
You did nothing wrong in port forwarding configuration.

Ok, Good idea

I was able to change the DVR Software (ShareBit) ports to:
Net Trans Port: 5191 <--- as it is
Web Server Port: 5192
FTP Server Port: 5193

and config VS to open port on 192.168.1.3 for ports from 5190 To 5195

Client now is working local on IP Address: 192.168.1.3:5191
WebClient is also working local on IP Address: http://192.168.1.3:5192

But :)

Client does not work on hostname: cam.biguae.com:5191  <-- working previously :)
WebClient is also does not work on hostname: http://cam.bigua.com:5192 nor 5191

I think this is all routing config problems related to this router.
1./ Does client resolve cam.biqua.com to your external IP?

2./ You should do port forwarding for each port in this case, of course, port forward a range port should work, but it seems your router has a little weirdo. So instead of 1 rule that you forward from external 5190 to 5195 to local 5190-5195, create 3 rules for each port 5191, 5192, 5193

3./ Change port for camera system is recommended, because camera web system have more flaws to hacker get through (Especially, traffic light and class monitorign system)

Ok,
My brother is able to connect to both: hahaha
Client on hostname: cam.biguae.com:5191
WebClient is also working on hostname: http://cam.bigua.com:5192

But I'm not yet ... sounds funny

Great achievement till now :)
If you was inside your network, you can connect via http://cam.biqua.com:5192

This router does not support translate back, so you cannot connect to your self by external ip address by this way. (If you want connect both inside and ouside with same URL, you must do some DNS stuff in your local network). But your brother does, of course.
