Need help with sFTP

Hey guys,

 

I am trying to setup sFTP server with one pool member, this is how my environment is setup:

 

Public IP --> F5 (VIP) --> sFTP pool (this is a vm and have no internet access).

 

This sFTP is in a vLAN who have no internet access also has it own default g/w not that same as f5

 

I have setup standard VIP and when I do that I can telnet (using public IP) to port 22 but I do not get any a welcome screen. When I change F5 to performance (layer 4) I cannot telnet at all. I have also tried to enabled SNAT on both VIP still no luck.

 

I can telnet to port 22 internally and I get the welcome screen no problem there and seems to be sFTP is working. How do I get this working publicly?

 

Thanks

    I've got a similar setup and have it working as follows.

     

    Public IP --> F5 (VIP) --> SNAT to sFTP Pool

     

    Am using a standard VIP with service port 22. Under configuration make sure you have the protocol set to "TCP" and HTTP profile "None" and FTP profile "None". No SSL profiles associated.

     

    If you still have issues try and do a packet capture on the F5, this may help you in narrowing down the issue.
