How to setup a virtual server on router

Virtual Server, also referred to as Port forwarding or port mapping can be setup with the router.

The setup of the virtual server depends on what you want to setup.

Virtual server is used to allow computers not on your internal network or computers on the internet to access a resource or service on the internal network.

For example:

Say you have an FTP on your internal network that you want people on the internet to access. To set that up go to the virtual server screen on the router and specify the IP address of the computer on the internal network that has the FTP server on it. The private port that you want to specify would be 21 because port 21 is FTP. The public port could be any number you want it to be, for ease of explanation lets just say it is also 21, that is the port the public would use to access the machine. For a computer on the internet to access the FTP server on the internal machine they would open up a web browser and type FTP://(WAN IP ADDRESS, found on main status page of router screen):21.

A better example would be FTP://

I have a Buffalo WBMR-G54 ADSL Router. The local IP address of the router is 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, 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, 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
> Status: Connecting to
> 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
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.

Trying to set up a vpn server on windows XP using

Did you already forward port 1723? I guess you have done that. To isolate it, try to bypass the router and setup or establish the VPN session there. If it doesn't work, maybe your ISP doesn't allow port 1723 or it's just the modem.

Cannot FTP at all behind Thomson tg585v7

Hi, your router will by default block all incoming packets from outside. You need to configure a firewall rule to allow tcp port 20 and 21 from outside and specify that it must be sent to the IP address of the pc running the FTP server software. Also make sure that your FTP server and firewall on the pc allows these ports in by checking your firewall on your pc.

Ftp server

What is the name of the software? Is that an FTP software?
Anyway if you are using DX-E401 Router you can enable DMZ (demilitarized zone) to your PC.

1.access your router configuration page (default ip:
2.go to advanced tab DMZ enable then type the ip address of your server pc
5.apply settings

after that have someone try to access the files in your pc.
if the software you installed is ftp software then have them access it by this


the "internet ip" is the ip address found in the STATUS TAB of your router under the WAN catergory.

If this software you mentioned is using any particular application ports, you will have to open those ports for your server PC.
In that case you will to configure VIRTUAL SERVER. It's the actual term used by dynex. for you to have a general idea how to configure your pc behind your router please go to this link

Virtual server configuration is in pages 22-23. It has detailed explanation of the terms used.

Hope this helps!

Port Forwarding

Port forwarding is a method that allows you to run a server behind the router. Port Forwarding opens a specific port to a computer behind the router, allowing all Incoming Traffic on that port to be sent directly to that server. It should be used to setup servers behind the router, typically Port Triggering (Answer ID 344) is a better choice for non server applications (Such as instant messengers and game servers). Below is an example of how to setup Port Forwarding. For our example we will be setting an FTP Server and a Mail Server that uses SMTP and POP3. FTP uses ports: 20 and 21 SMTP uses port: 25 POP3 uses port: 110 Getting Started 1. You must set a static IP address on the server. If you're unsure of how to do this please go to Answer ID 534 for information on setting a static IP address in Windows. 2. Once the static IP address has been assigned please go to your desktop and double click on Internet Explorer (Located on the Start Menu in Windows XP) 3. Once "Internet Explorer" opens, please type the "Address Bar" and click GO 4. The "Enter Network Password" window will appear. Skip user name and type admin (admin is the default password) as the password, and click OK 5. This will bring up the routers "Setup" section. Look under "Domain Name" and check what version of the firmware you're using. 6. You will need to click on the Advanced tab to the very right. Once the "Advanced" tab comes up please go to the Forwarding tab. Firmware prior to 1.32 This will not work with firmware prior to 1.32

Why won´t my FTP Client work with my D-Link router?

Make sure your FTP client software is set to passive. For security reasons the D-Link router does not deal with an active FTP client. An active FTP client can allow a hacker masquerading as an FTP server to gain access to your computer. Please contact your FTP client software manufacturer to determine how to configure the client for passive rather than active. Note: You will not be able to use an active connection through most NAT routers.
