So I can access the NAS through FTP on my home network, but when I try to FTP to it from work I don't get anything.

I am entering my home IP address, which I think is wrong.. since it's behind a router and is local.  How can I go about accessing my home NAS from anywhere on the net?

[Lucid]

1) goto Dyndns.com and setup an account
2) configure DynDns settings on DNS-323 Under Tools \ DDNS
3) enable portforwarding on your router and forward port 21 to NAS
4) setup the FTP server and add the users on the same page (Advanced/FTP server)

Hi.  I'm having problems accessing my dns-323 also.  Except mine's a bit different.
I can log into the dns-323 using FTP and my WAN IP address.
However, I can't transfer files.  Either upload or download.  Neither works.
I can log in and see the files.  My FTP client says it's transferring, but it does nothing.  Even letting it sit for a long time.
I have a fast internet connection.  10mb down and 1mb up.

I'm pretty sure it's a router config problem, because if I use FTP and connect to the local IP  (192.168.x.xx) I can transfer files with out any problem.

Any help please??

Try using FTP client software as opposed to your Browser (IE or Firefox). Many can be found on the Internet for free.

Filezilla's a good, open-source FTP client.

Lucid,

Any idea why port forwarding set up as you described would not work for me?  I have to enable a virtual server or it doesn't work.

Maybe you ISP blocks port 21. Try This:


STEP 1
1) Log into the DIR-655 Admin Page
2) Goto ADVANCED/VIRTUAL SERVER
3) Make Sure you ftp server is enabled (look for check mark beside name)
4) Don't worry about selecting the APPLICATION NAME(it only sets up standard info)
5) Change the PUBLIC PORT to a random number (25 for example, just make sure that no other setting uses the port you selected and make sure it is not another standard port such as 80 for internet etc. If unsure surf net to find out which ports are for which).
6) Make sure the PROTOCOL displayed is TCP
7) SCHEDULE select to Always
Set the IP address field to your DNS. (You can also select it from the COMPUTER NAME drop down field next to it.
9) Set the PRIVATE PORT to 21
10) Set INBOUND FILTER to Allow all

STEP 2
1) Goto ADVANCED/FTP SERVER

A) UNDER FTP ACCOUNT SETTINGS:
1) Select your users from the drop down list
2) Choose the FTP fpolder you want them to access
3) Select the permissions (read or write) from the drop down list
4) Click on the button Add

B) UNDER FTP SERVER SETTINGS
1) Make sure the port number is 21 (as you used in STEP 1 #9 above)

C) UNDER SERVER STATUS
1) Click on START SERVER
NOTE: look to see if the server is running.


That being said. an easy test to check the status of the server is to test it locally
For example subsitute you own numbers where you see []
1) Open you browser and type the following in the address field:

ftp://[USER NAME]:[PASSWORD]@[192.168.1.2]:[PRIVATE PORT NUMBER]
which could read like:
ftp://john:123d@192.168.1.2:21

Let me know how ths goes.

Cheers.

If I recall correctly (it's about a year since I replaced my D-Link router ) virtual servers are simply their name for port forwarding.

yes, it has the same function.

[marklyn]

make sure passive ftp is OFF for your client... that was my problem.  once i turned that off, it worked nicely!

Lucid,

Thanks for the checklist.  In your directions to me you say go to Advanced->Virtual Server.  In the reply to the previous poster, you say enable port forwarding.  Are you using these interchangeably? 

Here's my history:

I had previously had successful access to my DNS-323 ftp server through my Trendnet TEW-432BRP wireless G router.  They have a very different interface for firewall rules.  With the Trendnet, I was able to allow port 21 (FTP) to come straight through, which seems to indicate that Comcast allows port 21. 

I upgraded to the Dlink DIR-655 and initially tried to create the same rule using Advanced->Port Forwarding.  This didn't work.  My coworker showed me his setting and he uses Advanced->Virtual Servers to accomplish this.  I tried his approach (your approach) and it worked.  But I don't understand why Advanced->Port Forwarding doesn't work just as well. 

From my understanding, the only difference between port forwarding and virtual servers is that virtual servers doesn't allow a range of ports and it does allow one port to be mapped to a different port.

So to sum up...  I can do what I want to do with virtual server settings, but I don't understand why port forwarding doesn't allow me to do the same thing.  I _would_ like to combine the two for my ssh setup.

I'd like to "port forward" port 22 public to port 22 private.  I would also like to have a virtual ssh server on port 443 (so I can tunnel home from work).  Trying to set up two virtual servers in this way leads to a conflict in the Advanced->virtual server menu.  But if I create a virtual server for public port 443 and a port forward for public port 22, I am only able to get through the firewall on public port 443.

Any additional ideas are welcome.

Glad to help. AS for why you can't just port forward as opposed to using Virtual Server? Beats me. I far as I am concerned they are interchangeable (except of course for port ranges). That being said I remembered a while back a moderator advised someone to use Virtual Server instead of Port Forwarding but it was never explain why. For all intents and purposes as long as it works you should be fine.

In terms of setting up SSH. Are you trying to setup a secured FTP? If thats the case forget it. The built in FTP server can't do it. I have never had the need to do this either. I know if you download FONZPlug you can telnet ssh onto the system. That requires some setup but if you search the net for

1) Fonz Funplug v0.5 (http://www.inreto.de/dns323/fun-plug/0.5/); AND
2) Telnet (http://www.bergek.com/2008/11/13/dlink-dns-323-part-3-fonz-fun_plug/); AND
3) Linux Commands: (http://en.wikibooks.org/wiki/Linux_For_Newbies/Command_Line)

Fonzplug is not supported here and is still in beta, however, it is a great app and I haven't had any issues with it yet. Anyway, don't expect any help from the mods (understandably) with this since it is not developed by Dlink.

Cheers,

Lucid.

Lucid,

Thanks again for replying.  No, I don't need sftp - at least not yet.  I plan to learn about and try the fun_plug stuff down the road.  My only interest right now was to allow me to ssh to my home network by using the standard port 22 when not at work and the SSL port 443 when at work.  I can just use 443 all the time, although it's one more detail to remember at the command line.  Actually, I'm doing it right now (using a virtual server).

I wonder why port forwarding just plain doesn't seem to work? 

Cheers

[Lucid]

I hear you. Hopefully ECF will have an answer.

I am having a similar problem with FTP on DNS-323.  I have set up the virtual server to open port 21 on my DIR-655 FW 1.11 (1.20+++ is SNAFU...see below).  I have set up the user/password to a folder with R/W.  In Filezilla, I can log in to the FTP (at home on same IP range...).  But when I try to delete, copy, or change file/folder attributes (CHMOD) using Filezilla I get an error.  I don't understand why I can be logged in to the FTP, see the files/folders, but not be able to do anything with them.

Further, I have set both XP firewall and Kaspersky with the proper settings to allow "full" network communication with Filezilla.  Still, nothing...

I do believe it is a DNS-323 user/password setting that is fudgin the FTP.  The settings are there, but the actual settings are different with different levels set preventing it from doing anything.

Either that, or in addition...The FW for the DIR-655 is beyond repair and DLINK wants us all to purchase either the DIR-825, DIR-855, or DGL-4500...all of which those FW's are also beyond repair as well.  FTP...you don't need FTP with our "DLINK" routers.  We can't produce an actual working FW for anything so don't ask.
