Hi,

You can do as following to solve your problem:

1. The following commands must be executed in the MML Command - UGW_VNFC window. Enable the license for this feature.

   
   

   SET LICENSESWITCH: ITEM=Item, SWITCH=Switch;

   
   

2. Activate the Routing Behind MS feature for an APN.

   
   

   SET APNADDRESSATTR: FRAMEDROUTE=Framed Routing Function;

   
   

3. Set the maximum number of quintuples that a subscriber can use for all services.

   
   

   SET APNFLOWMAXNUM: FDMAXNUM=APN-specific Maximum Number of Quintuples;

   
   

4. Optional: Set the maximum number of quintuples that a subscriber can use for all services and enable automatic adjustment of the maximum number of quintuples for a single subscriber.

   
   

   SET SRVCOMMONPARA: FDMAXNUM=Maximum Number of Quintuples for Each Session, USERFLOWADJSW=User Max Flow Number Adjustment Switch;
