Hi everyone,

I'm trying to set up a Flashfxp client to connect to a NAS on my home network, but having some strange problems. I suspect it's due to being blocked by my work firewall/network, but I'd like to confirm.

I can connect locally via my home PC, and also when I'm logged into a VPN service (And my friend was able to connect via browser ftp).
When i try to connect on my work PC I receive the following errors:

When trying to connect via FTP using Explicit SSL (Auth SSL):

[R] Connecting to Home -> IP=xxx.xxx.xxx.xxx PORT=21
[R] Connected to Home
[R] 220 NASFTPD Turbo station 2.x 1.3.2e Server (ProFTPD) [xxx.xxx.xxx.xxx]
[R] AUTH SSL
[R] 500 Syntax error, command unrecognized.
[R] Failed SSL/TLS negotiation, disconnected
[R] Connection failed (Connection closed by server)

When trying to connect via normal FTP:

[R] Connecting to Home -> IP=xxx.xxx.xxx.xxx PORT=21
[R] Connected to Home
[R] 220 NASFTPD Turbo station 2.x 1.3.2e Server (ProFTPD) [xxx.xxx.xxx.xxx]
[R] USER Rune
[R] 331 User name okay, need password.
[R] PASS (hidden)
[R] 530 Login denied
[R] Connection failed

It seems strange to me that it actually allows it to connect, but then fails the authentication/password checks. Maybe there's some specific port being blocked by my work?

I'd appreciate any ideas on how I might be able to fix it/get around it.

Regards,
Greg
