This part - not so easy. For dialin users filters are applied PER USER.
So any filter applied to a PORT used for dialin is IGNORED. There is a way
around this, in that RADIUS knows the port being used and you can use profiles
in RADIUS for that port to apply the filter.

Sure - but why? RADIUS can block users from using specific ports, so they
can't even tie up the modem. They simply can't use that port.
