virtual server forward 22 to 2022

when I connected to the virtual server on port 22, I got the following:

ssh_exchange_identification: read: Connection reset by peer

when I used -vvv, I got the following:

    thanks a lot for all the responses.  I have been working with F5 tech support for 2 days. I might come across some hypervisor issue. F5 Tech is suspicious of this after they reviewed qkview. I am waiting for their findings.

    Is your destination pool cerrectly configured with (example) srvubuntu:2022 where 2022 is the port.

    i believe the virtual server only needs the tcp profiles, SNAT Automap for networks that are not directly connected,  persistence profile (if you load balance) and a Default Pool.

      All the configurations you mentioned are OK. 
      I need the virtual servers to serve multiple ports all of which need port forwarding,  ssh is one of them. 

      If I do not need port forwarding, all of them work fine, including ssh. But port forwarding does not work.

      thanks !!

    I did not many tests to notice the above is not relevant. It is related the special port ssh.
