<DIV><SPAN class=191053217-21092006><FONT face=Arial color=#0000ff size=2>I had
this sort of thing happen almost two years ago on a 2650 with apf (prior
version). We do have it runnning on a few Dell boxes (750, 1850, and 2650)
with out an issues today and on version back. I doubt it would be
kernel related. What are the settings in your
conf.apf?</FONT></SPAN></DIV>

then suddenly lock out all incoming connections, other than the backend IP,
sometimes restarting the firewall resolves this, but occasionally we may have
to leave it 10 mins or so before restarting where it will actually allow
connections again.<o:p></o:p></SPAN></FONT></P>
