Port Redirect

Hi FAJUMO , 

Why do you bother yourself by redirection. 

you can use Priority Group activation feature ( PGA )  within the pool. 

For instance :  Create a pool contains 2 members ( 10.10.10.10:2022 &  10.10.10.10:2023 ) as long as it's the same service. 

so the PoA from my perspective : 
1- add the 2 members within same pool with different ports ( no matter ) 
2- you can assign health monitor for each member independently/separately , this will make your pool to inherit the availability without assigning any health monitor over all the pool. 
so here both of members should be available. 

3- activate PGA feature with less than 1 , give the first member the higher priority/score to let the traffic to be forwarded to it and give the second member a lower score  to let bigip relies on it in case of failures in the first member only. 

4- none of your client will observe this change of ports as long as there is a full proxy in between client and servers , which dest address/port should be changed each time this virtual server. 

here you're all details about PGA : https://my.f5.com/manage/s/article/K13525153 & https://my.f5.com/manage/s/article/K45041241 

I hope this helps you 🙂
