I am having some issues getting FTP working on my new ReadyNAS NV+ (RAIDiator 4.1.6) and was hoping you guys could help point me in the best direction for troubleshooting. I have spent a couple of solid days troubleshooting and I have already opened up a case with Netgear, but I was hoping one of you guys could help point me in the right direction and save me a few hours on the phone with Tech Support.
My network (all hardwired with fixed IP addresses) consists of the following:
- Linksys WRT610N
- ReadyNAS NV+
- DLink DNS-323
- Laptop
For the last several months I have been using my DNS-323 as my FTP server by forwarding port 21 from the WRT610N to the DNS-323. Last weekend I purchased the ReadyNAS and intend on using it as my new FTP server. I directed port 21 to the ReadyNAS and am able to read/write to the FTP server from my local network. Once I try it from an outside network, I can write files to the ReadyNAS, but when I try to read them I get an extremely slow transfer rate. So slow that I have never sucessfully read a file in excess of 100kbytes/sec. If I redirect port 21 to the DNS-323, FTP works perfectly again. I have researched online, but none of the other suggestions have worked for me.
ReadyNAS FTP Settings
-Port: 21
-Authentication Mode: User
-Upload Resumes: Enabled
-Passive Ports: 3690 - 49999 (I previously had 5000-5020, but opened it up for troubleshooting)
- Masquerade as: {my domain name.com}
Here is what I have tried and some questions:
- I have opened up a DMZ to the ReadyNAS with no success. I believe this tells me that it is not a port forwarding issue. Is this an accurate assumption?
- I have used FileZilla and Windows Explorer as my FTP Clients with the same results.
- I noticed that if I do not also forward the Passive Ports to the ReadyNAS that I cannot browse the FTP directories. The DNS-323 did not require any addition ports to be forwarded besides 21. I'm not sure how to interpret this.
- My MTU on the Linksys is 1492. Per previous suggestions found on the web, I have changed my MTU on the ReadyNAS from 1500 to 1492 (restarting the FTP Server inbetween) with no improvements.
- I have changed my Masquerade As in the ReadyNAS from {mydomainname.com} to my WAN IP Address and have also tried my local IP address (restarting the FTP Server inbetween) with no improvements. I also tried a blank masquerade as with no improvements.
- On the client side I have been using TCPView to see which ports are active and it consistently shows port 21. When I do a read or write, one of the passive ports opens.
- I am trying to view the Linksys traffic by using their LogViewer (sucks) and now am trying KiwiLogger, but am having a hard time figuring out what information I need to look at. Can anyone recommend a good link on how to interpret all of the traffic I am seeing in KiwiLogger?
- I have tried two separate client computers. Both have success to the DNS-323, but neither can read a file from the ReadyNAS. To me this means it is not some local firewall or proxy issue.
I am by no means an FTP expert, but I can't figure out why one FTP server can work flawlessly while another flounders in the same setup. So my big question.... besides Active and Passive mode, are there different flavors or variations of an FTP server that I need to read up on? Can anyone recommend any other troubleshooting tools that may help? Can anyone link me to a quick and dirty guide on interpreting the KiwiLogger traffic from the WRT610N? Anyone recommend an additional troubleshooting thing I should try? Thanks in advance!
