Publishing FTP Server on ISA Server 2006

Posted on 2009-05-13
Last Modified: 2012-06-21
We are using ISA 2006 and I want to create a new FTP Server Rule such that it inludes port 20 & 21 with a range of ports opened and forwarded to the server for the passive (PASV) port range.

Can someone give step by step instructions to do this

Just create an outbound rule and add the FTP Protocol, then on properties of the rule enable write access.

Then Click Start, click Run, type regedit, and then click OK.
Locate and double-click the following registry subkey:

On the Edit menu, point to New, and then click DWORD Value.
Type NonPassiveFTPTransfer as the new value, and then press ENTER
Right-click NonPassiveFTPTransfer, and then click Modify.
In the Value data box, type 0 (zero), and then click OK.

Note To return this setting to the default value, set the NonPassiveFTPTransfer value to 1.

Now you should be able to upload and download using pasv ftp

The default FTP Server protocol has Port 21 as Inbound, which is the direction the traffic is coming from

Just create a new access rule, select the ftp protocol from internal netwrok to external network for all users then finish. Then right click configure FTP remove the read-only tick. Then do the reg steps already mentioned to enable PASV ftp

Will this change mean that clients can access the FTP Server with or without PASV enabled.

No i don't believe so, I believe most ftp sites have this as standard so don't think you will a problem. Microsoft HP all use this.
