No. The addresses don't exist until the machine that's doing the NAT puts them 
in.

If your LAN hub is non-switching just plug into that.
If your LAN hub is a super one then you can configure it to pass all data to 
one of the ports and plug ethereal into that. There's not much chance of that 
unless it's a big professional hub.

Otherwise get the cheapest non-switching hub you can find and put it between 
the LAN and the NAT machine, and put the etheral machine onto that. You will 
need to use a cross-over connection between the two hubs. Most (all?) hubs 
have at least one port that is, or can be, crossed over. Ensure that the 
ethereal machine is connecting to the hub at the same speed as at least one 
of the other two. (Even non-switching hubs still switch data between 10 and 
100Mbps.)
