I need to access a web server externally via port forwarding. i have a smcd3gnv

Do you mean that you need to access an server on your LAN from the outside world ?

The manual is on the second result of a google search for smcd3gn and the table of contents has clickable links.

The machine you run any inside server on needs a static IP address ( for example) and you configure the gateway so that your outside request to address and port ( gets mapped to your inside machine's IP address and the port you are running the server on ( for example.

If you are only using one internal web server just map port 80 to port 80 along with the inside IP and you can omit the port number in the external URL. (If you are running more than one server you should be able to figure it out.) Remember to disable external access to the router's configuration if you do this because that also runs on port 80.

My example mapped outside port 8080 to inside port 8000 just so they would be different. Remember that one outside port can be mapped to a single inside address and port. You can run two inside machines with a service on their own port 80 but they need different ports on the WAN interface.

How to portforward port 80

You must login to the router with a web browser and try to find the port forwarding options in the menu. You must then know the ip address of the machine you want to forward it to and create a "rule" to forward all traffic from port 80 to the ip address. But beware that port 80 is used by internet browsing and you could have problems due to that.

In order to get to the page you need to port forward you need to know your default gateway.

Enter those into your web browser, if nothing comes up then go to Start. Then click run(or search if you have vista) type "cmd" then type in ipconfig

There is where you can see your default gateway. Enter that into you browser. I t might ask for a password, it's usually admin.

Also a lot of the port forwarding issues are due to your firewall settings. Make sure you add the ports to there as well.

World of Warcraft

Sounds like you need to do some port forwarding.

World of Warcraft communicates on port 3724 with the TCP protocol. The patching process requires port 3724, 6112, and 6881-6999. Once again to download the patches for World of Warcraft you should forward the following ports.

3724 TCP6112 TCP6881-6999 TCP

If you can not forward ranges of ports and are only planning on having one computer playing WoW, just forward ports 3724 TCP and 6112 TCP. The 6881-6999 port range is mainly used where multiple computers on a network may be trying to play WoW at the same time.

Ventrilo: From their web site: Click on the "Port number" input box and enter the servers port number. The program will automatically display the default port number of 3784 but you can change this to what ever the server needs it to be.

So forward 3784 or the port number you chose. for a walk through on how to do the forwarding.

Hope that helps!

Port forwording

ok port forward if any has router this is easy ill get too others in momment

routers port forwarding features type in ip address in internet explorer search bar at top
router ip's start like this 192. type the whole ip in
this will ask you for password and that usually is the word "password" or "admin" threw that you can set the router port forward by going down the list

now for comps with out routers
goto control panel
then network connections
right click on your connection
goto properties
goto advanced
goto settings
you will be directed to windows fire wall
goto exceptions add program or port you want to forward

basically port forwarding is a program that keeps 2 comps from having conflict with each other running the same program and helps in monitoring ports for intrussions

Forwarding from seimens 5830 how to get access

You havent suggested what site you are wanting to forward one of your routers ports too, most people make this request for torrent download and/or gaming experience/improvement. Either way you need to know what port the software you are wanting to open a port for is currently using so you can tell your router which port to allow unchecked access.

I use this very informative support website for port resource info, click this link and choose your router type, in your case select Speedstream-5450 which will be the same setup as the 5830

That should take you to this page

Then select the software you are wanting to open the port for.IE: Utorrent or world of warcraft Etc... That will then open a detailed walkthrough on setting up rules for your routers port activity. You will need to follow the guide for each port you open, if the guide is not listed for the exact software you are using just read through the one supplied for Utorrent and change the port numbers to the ones you are using.
The software you are using should show you what port is in use at the time you are using it, some software may use a different port everytime you open the software or allow you to allocate a port permanently (which is not recommended safe internet practice especially if your ISP supplies your connection via a STATIC IP address, most use a DHCP allocated IP address)
Failing that you can find the port currently in use information using the command prompt- for winXP and Vista type c:/netstat-b for win2000 type c:/netstat-p Look for the software you are using it will be on the left hand side and look something like [Utorrent.exe] follow the line of info too the right and look for the 4-5 digit port number.

Wheeeew, Good Luck :0)
