Windows Firewall
Howdy, Wondering if anyone else has come accross this... but I set up my FTP server etc.. all good... accept when I go to log into it from a workstation on the network or external...Kept getting permission errors... Checked Windows Firewall... there was an acception for FTP in there.. with the correct port... killed it.,. added a new one... tried serveral time... Turned Firewall off... all works in terms of loggin in...I've found the same issues with Vista Firewall.. it just seams to ignore any setting added there.. WTF? Any help would be great. Cheers

If you're getting permission errors then it probably isn't firewall related. If a firewall was blocking the traffic you would likely get a timeout or error that the resource couldn't be found.What is the exact error?

Howdy, Thanks for your response. I'm afraid it is the Firewall. Turn it off and everything is happy. Turn it on and I get an error raised, which is a timeout but it suggests a permission problem. The error is: An error occurred opening that folder on the FTP Server. Make sure you have permission to access that folder. Details: The operation timed out As I say, this is also happened previously with Vista, ignoring the firewall exceptions. Cheers

Hello Brennon, I suspect that the Internet Explorer that you use to access the FTP server is in the passive mode. Passive mode FTP clients start by establishing a connection to TCP port 21 on the FTP server to create the control channel. However, when the client sends a PASV command over the command channel, the FTP server opens an ephemeral port (between 1024 and 5000) instead of the standard FTP transport port 20 and informs the FTP client to connect to that port before requesting data transfer. That will be blocked by the Windows Server 2008 inbound filter. Please perform the following steps to enforce the Internet Explorer to use the Standard mode (using the standard FTP transport port 20) to see whether it works: 1. Start Internet Explorer. 2. On the Tools menu, click Internet Options. 3. Click the Advanced tab. 4. Under Browsing, click to clear the "Use Passive FTP (for firewall and DSL modem compatibility)" check box. 5. Click OK For more information about FTP Standard (or PORT or Active) mode and Passive (or PASV) mode you may refer to: How to configure Internet Explorer to use both the FTP PORT mode and the FTP PASV mode in the Windows Server 2003 Family http://support.microsoft.com/kb/323446 Hope it helps.
