Although it is not possible for me to validate this with 100% certainty,
as far as I was able to determine all my clients are behind a "CheckPoint
FireWall-1 VPN-1."
Is there anything that can be done? Since the firewall is out of my
jurisdiction, my hands are tied. Unfortunately our "sysadmin" is just
another employee, overworked and underpaid, and with no expertise other
than being self-taught (highly commendable). The firewall servers
were set up by the people who sold the machines, and it is well nigh
impossible to have them send some support personnel.
This ftp server/firewall conflict has seriously crimped my ability to
update the NetBSD binaries. I am down to _one_ mirror which does not use
the NetBSD ftp server. When they switch over, I will be forced to give
up on NetBSD. I do not lie when I say I am VERY sad.

Totally false. I use the ftp clients bundled with NetBSD1.4.3 and 1.5.1,
and with Solaris2.6. I also use WSFTP by IPSWITCH, which, BTW, I can highly
recommend on the basis that their support team and programmers really care
about producing a superior product that follows the specs.
