Re: Westell 327W Firewall
Unfortunately, FTP is a nasty protocol to firewall. There is one connection to port 21 for passing commands. That's usually called the control connection. And then there is another connection established for transferring data (a file or a directory listing). For active mode FTP, the data connection is to an arbitrary port, but using port 20 as the source port. And the connection is made in reverse direction, with the server connecting to the client. For passive mode FTP, the connection is in the standard direction (client to server), but uses arbitrary source and destination ports.
A firewall typically has to look inside control packets passed in order to determine which ports are to be used in the data connection, and then set temporary firewall rules to allow that. Not all firewalls handle it well.
I don't think I have ever tried that with my 327w. I normally use either "http" or "ssh" for file transfers.

| How can I find out about using "http" or "ssh" for file transfers? As I have always used FTP, I have not found out the advantages or disadvantages of the other protocols. My goal is to be able to access my home files while I am on the road.
As of now, the only protection I seem to have on my NAS preventing outside theft is the name and passwords I use. They are all abnormal, so the bots trying to break in have not been successful (so far). But it is just darn disconcerting to look at the logs and see all the attempts. |

| You would need to be running an http server (web server) or an ssh server.
I normally using linux on my home system, so there is an ssh server automatically started. I don't know what is available for windows. I use putty as an ssh client on windows, but that's not a server.

Recent Macs are using unix beneath the hood (apparently based on BSD unix). Both openssh and apache should be available.
Note that I am not a Mac user, and I do not have any experience setting these up.
