No, all your filters (access lists) will apply to dialup users.
Each dialup user is on his own interface. So if you have an
input access list on your group-async/virtual-template/dialer/
whatever, any packets denied by the access list will be dropped
when received from the dial link and will not be switched elsewhere.
