hello.
before discuss about my problem sorry for my bad English.
Recently I setup a VPDN in ISR4351 and config radius,aaa, virtual -template,ip local pool ... no problem and user can connect to router as BRAS. Because I want to nat my private ip pool to a valid ip address it's necessary to ping my connected interface for nat action.
After user connected to router and create virtual-access session, user cant ping any connected IP in router except loopback interface which unnumbered in virtual-template interface.
trace from client show nothing and just * as time-out. But debug ip icmp show incoming traffic from client.
I just use "license accept end user agreement" command and reload router but nothing happened.
