Hi,
I am having an issue getting sftp to work and it seems to be caused by the ASA.
I can sftp from the open internet from my home pc to the destination using filezilla, but not using the same machine when I use the corporate connection.
Despite allowing my ip address throuhg the firewall out to all destinations.
Of course the sftp service providers blame our firewall, and it is hard to disagree, although when you start to look at the details it may not be as simple as that.
Does anyone know whether sftp is supported through the ASA - although it seems as though it is a much simpler protocol than ftp, i.e. no control and data channel, just a single channel.
The code version we are using is 9.4(2)11.
What is interesting is the ASA capture shows the 3-way handshake being setup, and then straight away, it received a FIN-ACK from the other side. Which is as if the server or server firewall is seeing the 3rd packet of the 3 way handshake as a FIN. Unfortunately the other side is not a Cisco device so there is not much in the way of logs.
Has anyone seen anything like this before?
Best wishes
Mike
I can attach captures is required.
