I Rule to translate destination ssh port to custom port

Mustafa_elAbd Can you please confirm the following?

1. Virtual server is 1.1.1.1:22?
2. What are the pool members for the VS in number 1?

Once we have that information we should be able to resolve this. At face value without those questions being answered I would say the pool associated to the VS should have pool members listening on <server_IP>:<server_port> which should look something like 10.10.10.10:22 and 10.10.10.11:22 if you had two pool members so you can simply change the pool member port to be 22022 and the F5 will balance the received port 22 traffic to port 22022 on the pool members without any iRule.
