Sure.

It depends a whole lot on the kind of traffic.  For instancem if I have
a couple bittorrents downloads, it gets into that weird state where
everything works except that a non-interactive connection to _some_
ssh servers (cvs.n.o being one of them) gets stuck after several data
packets are exchanged.  It recovers without problem once the bt
downloads are ended.

Of course, it's an old IPFilter, the one in 2.0.2, your vintage may
vary.

Well, the 4501 in itself will be the limitation, but it does the job
well for me.
