IP Camera Port Forwarding


The best way to find out what is being forwarded is to look at the traffic with the Wireshark program. You can install this from the Internet.

Wireshark is perfect for this but you have to learn how to filter traffic or there will be too much information collected. It is also regarded as (a bit of) a burglar tool so don't use it at work without permission.


I would recommend that you connect a PC to a wired port on the inside LAN and configure the router to forward outside requests to the PC. When you run wireshark on the inside PC with a filter that selects for tcp port 80 (or tcp port == 80) you will see traffic forwarded from the router.

Use your outside machine to request a page from the router's outside address and the port you are forwarding. If you have forwarding set up correctly, you should see a TCP connection attempt. If you are not running a web server on the inside PC, there will be no connection so you will only see the SYN packet from.
outside. If you have a web server on port 80, you will see a fair number of packets in both directions. (SYN -- SYN-ACK -- SYN -- some HTTP Headers an HTTP GET / a response and FIN -- FIN-ACK).

Once you see successful port forwarding (your are forwarding TCP packets, right?) at the PC, change the destination of the forwarding to the camera.

This is really technical but Wireshark is so good that it is quite easy to use.

I have a Buffalo WBMR-G54 ADSL Router. The local IP address of the router is 192.168.1.1. My Medion desktop computer connects connects to my Buffalo router using an Ethernet cable. I use the wireless...


> Zone Alarm free firewall and Avast antivirus have been installed on both computers

Your router is already acting as a "firewall" to block "unsolicited" traffic from reaching the computers on your LAN. So, unless you use Zone Alarm to block "outgoing" connections
(such as a computer-virus would try to make when "calling-home", there's little benefit
to using the Zone Alarm software.

> If I use Internet explorer to connect to http://myname.dyndns.org, Internet Explorer does connect successfully to the network. However, it invites me to enter the username and password for my Buffalo WBMR-G54 router - not for the storage drive.

While you are "forwarding" TCP port 21, you are not "forwarding" TCP port 80 (as used by the 'http://' protocol). So, when you connect from the Internet to your "public" IP-address, it is the router that responds, rather than one of your computers inside your LAN.

IMHO, it is "bad" that your router's web-interface is "exposed" to attacks from the Internet.
Either "forward" TCP port 80, or configure the router to use a _different_ port number for "remote management".

> If I enter the Router user name and password, that allows me to access the Router menus via the Internet, which confirms that my account at DynDns has translated the IP address successfully.

Correct. Hopefully, you're the only one who knows the correct username/password, and there is nobody that is doing "brute-force" attacks on your router, trying to login to "hijack" your router.

> if I use Internet Explorer or FileZilla to access ftp://myname.dyndns.org, I cannot connect to the router

Correct. The 'ftp://' protocol uses TCP port 21, which the router is "forwarding" to one of the computers on your LAN.

> or the storage drive - so I cannot access any of my files remotely.
> FileZilla reports -Status: Resolving address of bob1944.dyndns.org
> Status: Connecting to 78.144.xxx.xxx:21...
> Status: Connection established, waiting for welcome message

So far, so good.

Is FileZilla expecting a "specific" content in that "welcome" message, or will "any" response be "close-enough" ?

On a computer on the Internet, open a command-line prompt:

Click Start
Click Run
Type CMD
Press Enter
Enter FTP bob1944.dyndns.org
Press Enter
Do you get a "connecting" message?
Do you get a "connected" message?
Do you see the "welcome" message?

Note that the FTP protocol usually uses _two_ ports for File Transfer:

* port 21 for "control" (sending/receiving commands/responses)
* a "random" port for "data" transfers (including directory-listings)

It's this "random" port that your router is not forwarding.

However, some FTP-clients (probably including FileZilla) and some FTP-servers
support "passive" mode, where both the "control" and the "data" connections "share" port 21.

So, configure FileZilla to use "passive" mode, and _hope_ that your FTP-server supports "passive" mode.

You need to install a software that will manage your LAN's video recording. That software should work fine within your LAN and is usually provided with the Video Capture Cards where your cameras are connected. This software should have a web portal for you to access via internet utilizing your forwarded port. Thus, you must tell your video software to use your forwarded port for internet viewing. Without this web portal, you can't access your remote LAN videos via internet.

Need basic step-by-step instructions on how to install my router.


To Configure the Router with Internet Access
Connect to one of the wireless router/access point's LAN Ethernet ports, turn off its DHCP server, and give the wireless router a static IP on your LAN:
  1. Connect a PC directly to a LAN port on the wireless router with an Ethernet cable.
  2. Power on the wireless router/access point.
  3. Reboot the PC.
  4. Log in to the wireless router though a browser. (Usually 192.168.1.1, with User Name = admin and Password = password, unless you changed them from the defaults).
  5. Go to the LAN IP menu and disable the wireless access point’s DHCP server by unchecking Use router as DHCP server.
  6. Select LAN IP, and change the IP to 192.168.1.99.
  7. Click Apply to save the settings. You will lose the connection to the wireless router/access point , since its IP changed.
  8. Log in to the wireless router/access point with the URL: http://192.168.1.99
  9. Connect one of the wireless router's Local (LAN) ports to your existing network.
This completes the wireless router/access point configuration.
  • You can now log in to the wireless router/access point at its new address of http://192.168.1.99 and configure wireless features such as WEP and Access Control List
  • UPnP, DMZ, Port Forwarding, and Port Triggering are not used on the wireless router/access point, and it doesn't matter how they are configured.
  1. Configure the LAN IP address to be within the same subnet as your PCs.
    • Take care not to use an IP address already being used.
    • Limit the number of addresses in the DHCP range and assign an IP address outside of the range to the router you want to use as the Access Point.
  2. Disable DHCP on the wireless router/access point.
  3. Connect one of the LAN ports on the wireless router/access point to a LAN port on the Router.
  4. Configure the SSID and any security settings on the wireless PCs to match the wireless router/access point's SSID and security settings.
a. SSIDs must be the same on all wireless devices. (These are case-sensitive: netGEAR is not the same as NETGEAR.)
b. Tip: Make sure the wireless PCs can connect before configuring WEP, WPA-PSK, or other wireless encryption.

Access my lan from the WAN


I assume you want to log into your pc from another pc outside your lan. To do this you need to forward port 3389 to your pc.
  1. Make sure your pc (the one you want to connect to) has a static ip address. Also, it should have a password on the windows account you use.
  2. In the router, forward port 3389 (tcp) to the ip address of the pc.
  3. If you do this correctly, you can go to any pc outside your lan, and use remote desktop connection to connect. When you start the remote desktop connection, put in the wan ip address of your lan. If you did the port forwarding correctly, you will be asked for a user name and password. Put in the username and password for your user account on the lan pc and voila! - you are logged into your lan pc remotely.
Let me know if this works, or if you need some more help.

Problem using Wa1003A and Tew 432 brp to share my internet


lan wires are the same. lan wires used to connect your computer to your modem can also be used to connect your Wa1003A adsl router and TEW 432 brp.

you just got some things mixed up.

1. you should set your Wa1003A adsl router to bridge mode. At this point, it will just be "pass through" device and will not be the one who will ask for IP adds from your ISP.

2. configure your TEW 432 brp with your pppoe username and password. Your TEW 432 brp will now ask the network for the IP address to that it can connect to your ISP.

3. leave your lan wires the same.

Network routing problem with Axis Camera's


They would need to be on different TCP or UDP port numbers ... in order to access them from the Internet. I'm guestimating that on the LAN you can access all of them because they are on different RFC1918 IP Addresses (e.g. 192.168.1.10, 20, 30) but same port number (e.g. port 80 for web.)

Once you hop through NAT to get to the Internet you now only have one IP Address. The real Internet IP Address. So now you have to have different port numbers for 2 or more cameras. For example use:

#1 port 80
#2 port 8080
#3 port 8081
#4 port 8082

How about that?

And you will have to forward each of those ports to the correct ip address for the correct camera.

Hey BIgz19


It is not illegal, of course!


I assume you do have an ADSL or Cable modem connected with LAN cable.
You connect your modem to the wall outlet/splitter with a telephone cable.
Then then modem is connected with LAN cable to your router's WAN port and then two PCs to any of 4 LAN Ports.

Please follow these steps.

First RESET your Edimax router and disconnect all LAN cables if connected.

Connect one PC to one of the 4 LAN ports of your Router with a LAN cable.

Open My Network Places and then View network connections, or go to Control Panel and open Network Connections.

Right-Click on your LAN adapter and choose Properties, then double-click on Internet Protocol (TCP/IP)

Set to 'Obtain IP address automatically' and 'Obtain DNS server addres automatically' (click OK). Now you are back to the previous window. Click and check (if it is not) 'Show icon notification when connected' and once again click OK.

After a fiew seconds you should get (near to the clock in the the right bottom of your desktop), a Network icon and a baloon message that your NIC is connected.

Right-click on the network icon and click STATUS, a window will open
and then click on SUPPORT tab.
You should see:
IP Addres: 192.168.2.100
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.2.1

Open your browser and type http://192.168.2.1

Now login as:
admin (default)
and password is: 1234 (default)

Click on GENERAL SETUP on Top-Left, and then on WAN (on the right side) and choose
PPPoE.
Click on 'More configuration'
Type your User Name and Password you have from your ISP.

Now Click on APPLY, and again APPLY !

The Router will restart in 30 Sec, and your NIC will reconnect.

Now connect your Modem to a WAN port of your Router with LAN cable.

Now:
if you've typed your User Name and Password correctly in PPPoE fields,
and
if everything is OK with the service from your provider,

you should now be on Internet.

If not, then please check your User Name and Password with your Internet Service Provider, and ask them if they can see your router.

Now, get to the other PC and do the same above.

Connect the NIC with LAN cable to another port of your router.

The second PC should be on Internet, too.

You should check if both PCs are in the same WORKGROUP !
Right-click on My Computer, click Properties, then click 'Computer name' tab, and down on CHANGE. In the Workgroup field type the same as the Workgroup name of the other PC, then APPLY and OK.
This action need a REBOOT. Do reboot!

That's it!

Hope it helped.
