How to do port forwarding in Cisco 2921?

Question

Computer networks

Hello everyone,
I did this
ip nat inside source static 172.16.1.10 whiteIP extendable
as I understand it, all ports on this IP are gone, I have access to this sideboard,
now I need to access another server on a specific port
, delete that rule, it turns out like this
Static entry in use, do you want to delete child entries? [no]:
I need to forward ports 80 to another IP and port 21 to another IP
part of the config as I have.

no ip http server
ip http access-class 23
ip http authentication local
no ip http secure-server
ip http timeout-policy idle 60 life 86400 requests 10000
