You need to configure the Service Interfaces for the servers again with the new port.lie the below example:-
Existing Server config:-
---------------------------
service Test-001_Int1_8080
ip address <>
port 8080
protocol tcp
keepalive type tcp
active
new Service interface config:-
--------------------------------
service Indy-001_Int1_3366
ip address <>
port 3366
protocol tcp
keepalive type tcp
active
then it is the new content rule and other config stuff..
