I have several Workstations with Digital Unix v3.2 behind a DEC
firewall hosted on a DU 3.2 workstation as well.

I would like the workstations to print through the firewall on a Print
Server on the non-protected network. I tried to setup a proxy from
the generic relay program available, but this doesn't work because the
PrintServer protocol doesn't work with a given port number, but
rather uses port 170 for connection, but then negociates another port
with the printer for actual data transfer.

Does anyone know of (or has developped ?!) a dedicated relay program for
DEC PrintServer protocol ???


Thanks
