Dear Group,
                  I use Openbsd on a stand alone computer
with dial -up internet.I use userppp for internet access.
I wish to use the built in filtering of this program.
                   Brian Somers the author of this program 
has kindly sent me his suggestions on what to do but I
hesitate to use what I don't understand. I am having 
trouble finding out what udp port 525 is used for. Also
what is meant by tcp finrst. I think I get the rest.
                     Could anyone explain or point me in the 
right direction?
                                        John Duncan
