Hi Stephan,

 

I'm actually trying to configure SFTP (not FTPS) on port 22.

 

This should be fairly simple but or some reason it doesn't work for me.

 

I have created a node with my physical server, assigned it to my ftp_pool using port 22, used that pool for my virtual server but no luck.

 

I have tried to configuring the virtual server as "Standard" and as "PerformanceLayer4" and still nothing.

 

Is there anything else I need to do?

Hi Domel, a virtual server on TCP/22 with snat automap and a single poolmember configured to TCP/22 should work fine. Done it three times for different clients in the last couple of months. You can try to run a tcpdump to track traffic: tcpdump -nnni 0.0:nnnp -s 0 -c 1000 host The dump should show all traffic from this client and how it is forwarded to the real server (via the "p" flag in the interface specification; available since TMOS v11.2.1+). There are some extensions (the "n" aka "noise" flags) showing, which virtual server is handling the traffic. Maybe this helps to figure out what´s going wrong. Thanks, Stephan
