Hi Chaz,
I will add my input to the overall information that you will probably get in
response to your
query.
Hopefully some of what I say may be of use to you.\
Cheers,
Simon Long

I should just come down to IP connectivity. If you can ping it and if there
are
no ip filters preventing you you should be able to achieve your aim. But as
regards the management of the Firewalls themselves - this is trickier.
> 2. What ports need to be opened up to allow clients access a Netview server
Probably I would just grab a copy of the Release Notes which contain the
port use and complement the detail you get there with something like "netstat
-na" from the
client and "lsof" ( for correlating daemons to ports ) - let me know if you
don't understand what I mean.

It would probably come down to a strict analysis of:-
1. How many filter inclusions you need to make ( more for a standard client
connection )
2. What the relative bandwidth utilisation is ( from memory the xwindows
approach
would be heavier ).
3. The perception of exposure inherent to utilisation of unprotected X
traffic.
