Hi,

firewalling and QoS enforcing are the functions of a packet forwarding 
plane, and are very much OS / platform specific.  XORP as a portable 
routing protocol software does not (yet) provide interfaces to such 
OS-specific forwaring plane features, though you might wish to take a 
look at Vyatta OFR (www.vyatta.com), which while using XORP in its 
control plane also provides an integrated interface to forwarding plane 
functions such as NAT, firewall, VLANs etc.

Hope this helps,

Marko
