    Ok I am trying to teach myself the setup and operation of an FTP server. I an using Cerberus FTP server and FlashFXP as my FTP client on my home network. My gateway router is a Linksys BESFX41. I have my private network behind the router working fine. I am able to ftp from my 4 computers to the FTP server computer.

    My question is how do I make my server accessible from the internet. I have no idea what address to give anyone to access a user account on my server. I have forwarded port 21 to my server PC.

    But if I want to access the server from the internet what address would I have. Let's say for example my user account is FRED. Say my outside WAN IP for the dsl modem is just for example. What address would I use to access my server for the account fred. Would it be fred@

    I am at a newbie loss here can anyone give me some help?

    You need to use a dynamic DNS service.

    My ISP assigns me a dynamic IP address (to my modem), which is the IP address I need to access my router from the internet (WAN) side.

    I could either use this IP address (but it might change) or use a dynamic DNS service which gives me a domain name that follows my changing IP address.

    I use DynDNS:

    It's free, but you will have to go back once a month to 'renew' or validate your account - DD-WRT firmware I think does this for you!

    I use Serv-U ( ) for my ftp server, and access it by

    I use Appache ( ) for my http server, and access it by

    ok that sounds great but how do I go about setting up dynamic DNS om my Linksys BEFSX41 router?

    Sorry if this is basic stuff but I'm a novice at this.

    Go to the Linksys WWW site, then downloads; get the manual for your router. There is a section on DDNS, for which you will need to register with the site - you need to get your domain name sorted first.

    The Linksys manual clearly explains what you need to do...

    Chill out mate. You've been a member here only 3 weeks and you flame people who are novices trying to learn. I didn't even know what DDNS is let alone be able to set it up on my own. If networking a router was that easy there would be no need for help forums now would there??

    Don't bother answering I'll find help on another more friendly forum.

    Sorry you thought I was flaming - I wasn't.

    You want DDNS to work, then you have to do two things, like I said.

    Go to (specifically ) and register a domain name and your IP address (the one for your modem; determine this by going to:

    I have a WRT54G, I do NOT have a BEFSX41. I checked to see if DDNS could be set up on your router (for which you did not specify version or firmware you are running!) by going, again like I said for you to do, to the Linksys WWW site:, then the Downloads section, choosing you rrouter model and looking at the manual: *this is the manual for the v1 version of your router. v2 is here: (slow to download)

    It spells it out quite clearly step by step how to set up DDNS - far more clearly than I ever could.

    Short of having me come round and do it for you, I don't see what further information I can give you?

    Generally speaking, you don't need DDNS to get started, you just need to install your ftp server software on the machine you want to act as the server, then port forward ports 20 and 21 to the ip address of that node.

    Then, provided you've got it set up right (file and client access), you'd go to your browser and type:

    As long as you have your ports forwarded properly and all internal settings are correct, you should get a "two field" log on prompt for access to your ftp server.

    This is a real general and basic answer, but, if the bare minimum is configured correctly, you should get this far...

    This is all fine until your ISPchanges your IP address (for example if you power cycle your modem), hence the need for DDNS...

    Which is what would be assumed "once" he gets the basics established "which" is first getting connected...

    Another way is to "publish" your IP addresse using a small free software like Watch Wan IP ( ).

    You'll tell the software how to know your IP address (e.g. or or many others to find with google). Then the software can send a small file containing your IP address on a web server that you can access anytime. I use the free space on a server of my Internet access provider

    In this way, you don't have to suscribe to any system like
