- I thought everyone had heard about this problem by now. The DEMFA controller
- is afflicted with a problem similar to that of the DEBNA in that it ignores
- incoming broadcast packets. Since ARP requests are broadcasts there is no
- ARP reply, and thus no access. Making an outbound connection updates the
- ARP tables in the router, allowing inbound connections to go through.
-
- Contact DEC Field Service and ask to have the DEMFA microcode updated to
- at least version 1.4.
