- Now, what are the TCP/IP packets doing there? I understand the Appletalk
- packets, but Cecil begins to barf up these TCP/IP packets right after it
- boots. From two hosts that certainly do not have an Ethernet address the
- same as Cecil. Cecil is a Gatorbox I'm experimenting with. I'm trying to
- get subnetting working. Have I got the crazy thing configured wrong? Is
- it picking up and retransmitting every packet it sees?

- P.S. I know this isn't exactly "INFO-Multinet" but it is TCP/IP routing
- and so forth.
