We had similar problems until our network guys installed Surrogate
Sockets (see http://www.edu-tec.com/surrogatesocket/)

I may not have the details 100% correct, but here goes. Using this
product got around the problem of having unregistered/unregisterable
IP addresses on the HP 3000 side of the network. Each ftp site you
want to reach from the HP 3000 has to be configured in Surrogate
Sockets. Essentially an alias IP address is assigned for the ftp site
and you use that alias when ftp'ing from the HP 3000. For example, to
connect to HP's ftp site at 192.151.11.14, I ftp to 10.1.21.4.
