The client never even attempts to connect to the Data port as it never receives theĢ27 Entering Passive Mode (192,170,1,1,19,41).
This is totally weird - it's like the whole TCP conversation just ends after the server sends the reply to the The client machine (Wireshark logs in the previous post hint at that as there is just nothing in the Client after the PASV command is issued). The reply from the FTP server 227 Entering Passive Mode (192,170,1,1,19,41)., which contains the Data port range info for the client to connect on just doesn't appear to be getting to I've spent the whole day looking this one over, researching and trying different things and I am still stuck on this: The client side times out, never apparently making the connection - and it rightly so it would appear as the port number looks to be 57665 (correct me if I calculated this wrong) which isn't within the range I that I opened in the Firewall - or in theįTP Firewall Support settings in IIS on the FTP server (now that's a problem.).Īh, man I'm tired now.

Tools (and hence isn't open thru the Firewall appliance). The only problem is now in the switch to PASV mode - for some reason (and I will investigate settings on the FTP server after posting this) the server is telling the client to connect to a data port that isn't in the range I specified in the IIS FTP Managment Once I added these, I was able to establish the control traffic over port 21 between the internet based test client and the internal FTP server. I've checked and re-checked every setting in all of the firewalls and in the FTP service/IIS.Īnd, thanks for putting my attention back on the Hardware firewall - there was indeed a problem with it's settings - I only had Destination NAT rules in place and I needed to add in a couple of Source NAT rules to alter the source of the traffic to be the I'm going nuts trying to figure this one. It's like the FTP server machine isn't accepting any traffic that doesn't originate from the local subnet!? And yet, this same machine is happily hosting HTTP and HTTPS websites that are served up on the internet and deals with internet sourced traffic for See them! Likewise in the FTP logs - no trace can be found - which would follow as they don't appear to be getting noticed, even by the firewall software? And yet WireShark clearly shows them reaching the machine.

I've enabled logging on the FTP server machine in Windows Firewall for both rejected and accepted packets, under each of the profiles (Domain, Private and Public), and interestingly enough - the packets are never logged! It's like Windows Server just doesn't Server machine and can see the packets landing at the server on port 21 - but the server does NOT respond? I've run diagnostic logging on our firewall appliance (a SnapGear SME550) and can see the packets being recieved from the test client and then being forwarded on to the internal FTP server machine. Simply times out with either FileZilla or using a Telnet client session. However, I am completely unable to access the FTP service from the Internet - and yes, I have opened ports -4910 in our hardware firewall appliance and forwarded them to the Windows Server hosting the FTP service. This all works fine from any machine on the LAN using FileZilla or even testing manually using a Telnet client. Tools in IIS and have opened the necessary ports to allow passive mode FTP access (port 21 for Control Traffic and a restricted port range of 4900-4910 for Data Traffic) I've then published a couple of existing basic public websites using the FTP software, using the FTP managment

I've downloaded and set up the FTP 7.5 server software from Microsoft, on a Windows Server 2008 Enterprise SP1 machine with IIS7 (actually a Hyper-V VM).
