secure subnet problems

[Scott_Busse@mindlink.bc.ca (Scott Busse)]

I'm having the same problem as David R. Strip described, wherein any
attempts to access the namespace server (3650, on Genera 8.1.1, named
MindsEye or M)are refused.
  In one case, I'm trying to put and get files from the server with
TCPTP on an amiga. I had no problems doing this when the server was
on Genera 7.2, but now I get an error message to the effect "Amfar
(the Amiga) refused FTP access." This error cropped up when I upgraded
to 8.1.1.
  In the other case, another 3650 (named Sentia or S) previously had
no problems under 7.2. Now alot of water has passed under the bridge
since I started trying to fix the Amiga problem, and somewhere some-
time the inter-Symbolics net started showing the same problems
described by David. This case is not as important to me as the Amiga
problem, since this machine has intermittent A-Mem problems anyway,
but I'm assuming the problems are caused by the same beast.
  I'm using bogus INTERNET addresses (M - INTERNET 200.0.0.5, CHAOS
401 : S - INTERNET 200.0.0.2, CHAOS 402 : A (amiga) - INTERNET
200.0.0.6).  I set the INTERNET Network object subnet masks to
INTERNET-SUBNET-MASKS (("200.0.0.6" "255.255.255.6")) as was
described in David's reply, to no avail (actually it was the user
property field in the INTERNET Network object), to no avail.
  Enable services ALL was issued, I tried rebooting, all having no
effect. I'm probably missing something, can anyone tell me what it
is?
Thanks for any help!  Scott
