Framed-IP-Address Help

[Aurélio de Souza Ribeiro Neto]

   Hello Everyone,

       I need help.

       In my default configuration file I did this change in authenticate
   session:

           Auth-Type mschap {
                   mschap  {
                          reject  = 1
                       }
                       if(reject) {
                          update control {
                            Pool-Name := "mkt_pool"
                          }
                          update reply {
                             Mikrotik-Rate-Limit := "2M/2M"
                          }
                          ok
                      }
           }

       This change is for give an IP from another POOL if the user is with
   invalid credentials.
       All works fine if the IP comes from DHCP, but if the user have a
   fixed IP then the IP is not changed.

       How can I remove the fixed IP to force the user to receive an IP
   from pool that I choose?

       Thanks

   Aurelio
