Want to know i-Rule to control source port change when conflict

Hi guys.

 

I got some problem and need i Rule command to control.

 

ltm snat /Common/OMWS-EIA_NAT { origins { 10.221.140.39/32 { } 10.221.140.40/32 { } 10.221.140.41/32 { } 10.221.140.42/32 { } 10.221.140.145/32 { } 10.221.140.146/32 { } 10.221.140.147/32 { } 10.221.140.148/32 { } } translation /Common/175.207.88.48 vlans { /Common/Front } vlans-enabled }

 

due to lots of origin, source port conflict on server side(SNATed IP:'port') and change.

 

behavior of port change is convinced but some times changed to specific port.

 

Specific port means for security reason -> blocked.

 

I have opened case, but there is not clear answer so I`m look for i-Rule.

 

when source port conflict and change event occur, want to except specific port.

 

Does anyone give some help to build i-Rule?
