NimbostratusListening port of pool members about SFTP virtual server.
Hi all
I would like to create a virtual server for SFTP. Does it work with a virtual server listening port 22 with address translation and port translation and the pool members are listening port 21?
I tried this but failed. But If I change the listening port of pool members from 21 to 22, connections could be established successfully.
How could I make a SFTP virtual server works with pool members listening port 21? Or this couldn't be done?
THX

SFTP works over SSH so a VIP and Pool members should only need TCP/22 (assuming the SFTP service on the pool members are enabled on TCP/22)
alex100_194614If I understand correctly you want to do SFTP (TCP 22) on the clint side and FTP (TCP 21) on the server side with Big-IP in the middle doing the "magic". That wouldn't be possible due to nature of SSH protocol and encryption. Your SFTP servers should be listening on port 22.
