Need SSL firewall

[David Mazieres]

I recommend Darren Reed's IPfilter package, which comes with OpenBSD,
and installs easily on FreeBSD and NetBSD.  It also works with SunOS
and Solaris, and I think even more operating systems.  It is highly
configurable.  Blocking all incoming TCP connections except to a few
host/port pairs should be quite simple.

You can get it at ftp://coombs.anu.edu.au:/pub/net/firewall/ip-filter
