>Description:
ppp(8) does not update filter rules with sticky macro HISADDR after negotiating IP-addr.


>How-To-Repeat:
make ppp.conf record with:
  set ifaddr 217.150.59.131 192.168.253.2-192.168.253.99
  set radius /etc/radius.conf
  set filter in 0 permit HISADDR 0.0.0.0/0

At start ppp(8) select client ip from pool (192.168.253.42) and set filters.

After authorization with radius with attributes Framed-IP-Address:=217.150.58.197 packets blocked:

>Fix:
Setup (or update) filter rules with macro in /etc/ppp/ppp.linkup
