There seems to have a solution that has been discussed sometimes ago:

Somebody on the net was complaining that he only sees questions on the
net. Never the solutions.

My problem was solved recently ---

The problem
============
I had a network problem with our Explorer-II (TCP/IP protocol).
Whenever it received a broadcast message (eg:with the address 128.125.0.0),
it responded by sending an ICMP error packet. This cluttered our network.

The solution
============
Based on the suggestion form Paul Fuqua
I found that the :INTERNET-SUBNET-MASKS attribute of the :NETWORK entry
in the namespace of my explorer was NIL. I updated it to
("128.125.0.0" "255.255.0.0").

Hotline (512)250-7404 struggled for a week and came up with this patch.
Add the following code to the case statement in
the function "(defun-method portmap-dispatcher (svc-request stream)"
in the file sys: rpc; portmap.lisp

 (case
   ..
   ..
   ;;*******************ADD THE CODE BELOW*****************
   (#.pmaproc-callit
       (ignore))
   ;;******************ADD THE CODE ABOVE***************
   (otherwise
     ..
     ..
  )
This presumably prevents the explorer from giving out an error
on broadcast messages.
=============

After these two "fixes" I have had no problem with the explorer
at all. More power to Hotline and Paul Fuqua!

V.V.

p.s. Yet to figure out which one of the above fixes actually solved
     my problem.
