Thanks, but each machine is a dedicated machine.
I did pull the NIC from FBSD and put it in W98 to check to MAC.
It does have a valid MAC.
I then put it back in the FBSD box and did the following on W98
arp -s 192.168.0.1 ff-ff-ff-ff-ff-ff
(They are separated by '-' on the pc. duh)
Then tried to ping the FBSD box. No luck.
Also tried
arp -s 192.168.0.1 mac-address-read-from-pc
and tried the ping. Still no luck.
I think, unless someone else has a suggestion, that I am at the end of
my rope and have run out of spare cord.
Does anyone else have a simple gateway/LAN setup. And if so, what is the
MAC on the inside NIC?
Also, my current path is a dead end, then I only see hope by getting a new
NIC. Can anyone suggest a inexpensive NIC? I don't won't to spend $100 for
a 3COM.
Thanks
Jim
