Really need to get this to work for me.

I know a lot of people have gotten this to work and a few have had problems.

My issue is that I cannot connect to the FTP server on the DNS-323 from the internet. I changed to port to 35 and in my Linksys WRT54G router I forwarded the port to the static IP address of the DNS-323.

Heck, I even put the DNS-323 IP in the DMZ host and still no luck.

I did setup an FTP server using software on my laptop on the same port (35) and that worked over the inernet. So the issue is with the bloody DNS-323 FTP not being accessable over the internet.

I've been able to connect to the DNS-323 FTP from within my network though using the static IP address. THis is obviously useless to me since I want to connect using my router IP address instead and be able to access the FTP over the internet.

The error I get from the FTP client is that the connection timed out. I am sure that the client can't even find an FTP server.

My DNS-323 is upgraded to FW 1.04, not sure what my Linksys FW is but I willl find out and post that soon.

Please help me, otherwise this product will not have the same appeal and I will have to sell it.

Thanks for your help and replied.

Ok - so .....

1) you can access your DNS-323 on port 35 from the local network
2) you've told your router to forward incoming port 35 to the static ip address of the DNS-323

The router knows how to get from traffic the internet to the DNS-323, the DNS-323 knows what to do with it, but how does the traffic get off the local LAN and back to the internet ....

Did you set the default gateway address on the DNS-323?

TheCrescent · 2008-03-23 04:55:14

Yes for #1 and #2.

As for your third question I'm not sure what you are asking. I have 1 computers connected to my router via hard wire ethernet connection and 2 (desktop and laptop) through wireless G connection. All these systems are able to access the internet through the Linksys router.

I'm not sure if the DNS-323 can access the internet....not sure how it would.

The Default gateway is set correctly to 255.255.255.0 I believe and its the same was what the search utility reports found on D-Links website.

I;m just wondering if everyone has to do the Telnet workaround found in Wiki: http://dns323.kood.org/howto:open_ports_ftpd

I hope not, as I wish for this to work out of the box.

Hold a minute - you're not sure if the DNS-323 can access the internet? If it can't then you have a problem, because if it can't, then it can't respond to a request from the internet, can it - sounds like that might be your problem? Well, lets' fix that.

I'm not talking about the subnet mask, I'm talking about the default gateway - this is basic tcp/ip

When a host using tcp/ip needs to send data to a second host that is on the same network, it simply puts that data on the network using the mac address of the second host - believe it or not - ip addressing is NOT used for local LAN communication, it's all done using the mac or ethernet hardware addresses.

The problem that arises when the second host is not on the local LAN, and the first host must now figure out a way to route that data to the second host on the other LAN - and it's not smart enough to do this on it's own, so you have to tell it, and you do that by setting the address of the default gateway.

Once it knows the default gateway address, the first host will now send the data to the default gateway, with the ip address of the second host that it is intended for, and it will expect the default gateway to know (or to be able to find out) how to route the data so that it gets to the second host.

Look in Setup/LAN - see where it says gateway ip address? Enter the internal ip address of your default gateway there.

And in case you haven't figured it out - the default gateway, the device that knows how to reach the other networks would be your router

oh - no - you shouldn't need that telnet work around - ftp works straight out of the box - provided everything else works, and I think you've already tested that by connecting to your laptop, so you were almost right when you said....

I did setup an FTP server using software on my laptop on the same port (35) and that worked over the inernet. So the issue is with the bloody DNS-323 FTP not being accessable over the internet

Just a wee bit off - more like the DNS-323 is sitting there wondering "how do I get this stuff to this daft bugger, I don't where to send it"?

Good luck mate.

TheCrescent · 2008-03-23 06:36:14

Thanks man that was my problem...I had the wrong default gateway address assigned to my DNS-323...now everything works.

This saved me a lot of time and headache...

Now moving onto getting the UPnP to work with my Xbox 360

fordem · 2008-03-23 16:58:36

Ahh - I take it you have read about the risks of using ftp across the internet then?

You know - your basic lack of security, the inability of the DNS-323 to log who connects and where they're connecting from, and stuff like that?

TheCrescent · 2008-03-23 17:58:54

I know there are security holes but I'm not sure what they are...is there a good read for this somewhere?

I'm assuming my data is safe considering I only created a few accounts for trusted family members.
