Remote Access over WAN

How can I setup port-forwarding to the ReadyNAS?

Port-forwarding is a way of selectively allowing access from a WAN (Internet) to your LAN through your existing router firewall. Only the network protocol "ports" that you forward will be allowed access to a particular box on your LAN. For instance, if you want to enable only FTP access to your ReadyNAS, simply forward ports 20 and 21 on your router to the ReadyNAS IP. You can do the same for HTTP or HTTPS by forwarding ports 80 and 443.

Each router will have a slightly different method to allow this option. Here's a link that explains how you would do this with a lot of the routers on the market. This link courtesy of MrCyberdude.

How can I setup my ReadyNAS for FTP access over the Internet?

Yes, you'll first need to configure your router for port forwarding. Ports 21 and the passive port range, which can be configured in the Services tab, must be forwarded to the ReadyNAS IP address. Also set the "Masquerade as" setting to your external IP address or domain name.

How do I setup the ReadyNAS for anonymous FTP in non-Share security mode?

In the Services page, select Anonymous for FTP mode. Note that Anonymous FTP is the only mode available in Share mode.

I can log into the ReadyNAS, but when I try to transfer files, the transfer rate almost immediately goes to 0 and eventually times out. What's wrong?

Try changing the MTU on your router to 1492. This is often needed when the ReadyNAS is connected to the Internet through a Cable-based broadband service.

How can I access my ReadyNAS through FTP when my ReadyNAS is behind my home firewall and my client is behind my school/work/etc. firewall?

You will need to setup the ReadyNAS for passive (PASV) FTP. To do this, go to the Services page and setup the options under FTP. In this case, you will need to select a passive port range (in most cases, a small range of 10 to 20 ports will do) and forward it from your router to the NAS. You will also need to enter your public domain name or IP address in the Masquerade field.

I get errors when I try to issue FTP commands. My logs mention extended passive mode.

Try forcing your FTP client to use active (PORT) or standard passive (PASV) mode. Extended passive (EPSV) is only needed to IPv6 networks, and is not supported by the ReadyNAS.

I can't seem to access certain files and directories in my FTP share.

Depending on the security mode and FTP mode, you may need to adjust the permissions on these files and folders to permit access through FTP. In Share mode or Anonymous FTP mode, the NAS will see an FTP user as a user named "ftp". Therefore, files and folders will need to be accessible by this user for them to be accessible via FTP. The easiest way to allow access to a file or folder is to go into Windows, right click on the file and select Properties, then select the Security tab, and add the required permissions to the "Everyone" setting.

In User-based FTP mode (available in User and Domain security modes), the NAS will see the ftp user as whichever user's credentials you used to login. Therefore, if you logged in as user "ewok", the NAS will see you as "ewok" and will allow you to access files and folders that are accessible by "ewok" when mounting the share in Windows.

I can access my ReadyNAS over FTP using an FTP client, but not with Internet Explorer.

Try putting your internal or external IP address (depending on whether you will be accessing the NAS from a server on your local network or through the Internet) in the Masquerade As field in the Services page.
