Andy,
  It sounds as if you've had your share of troubles with the netra
solution. I was wondering if you could forward some advise. I am looking
into a Netra solution for one of my contracts. All I need is http
firewall service between one http server on the netra box and 400 known
clients. What I was wondering, is can you configure firewall first for
secure http? If so, how much athourity do you have over the traffic, how
configurable is it? With the light version can you specify which port
you wish to use for each services' traffic, i.e. can I use the  fifth
service for my own TCP communications protocol? Also, does the netra
come with all the Solaris 2.5 modules for a development system or is
that cut down as well?
Thank you
