I am using FileZilla on a windows PC to share out FTP. I had this configured to support active and passive ftp through a linksys rv082 gateway/router.
I have upgraded to the WatchGuard Firebox x550e. All other services work fine using the same configs as the linksys. Active FTP using command line or a ftp client works great, but passive does not work. Using a web browser, the password/login challenge dialog comes up, but hangs beyond that. Connecting to the server within the LAN works with no problems.
I put through ports 20-21 and passive ports 5000-5025. i also set filezilla to use the static external ip for passive. The linksys worked fine, but the WatchGuard box does not like this.
I am not using a FTP proxy. I am using a custom tcp filter for 20-21 & 5000-5025 from any external to a static NAT.
I am talking to support, but their second level support is not understanding this, They claim ftp is working, but are not trying a browser. I have been down now for 5 days and I am getting a bit upset and so are my customers. Any help would be appreciated.
