This is fascinating stuff. I have never used these tools before.

Although nslookup still works with both name servers, I am not seeing the same 
network activity with tcpdump.  Here's what I get when the router is listed 
first in /etc/resolv.conf:

15:22:25.452062 IP 192.168.0.100.38082 > 192.168.0.1.53:  46610+ AAAA?

1.0.0.0 (50)

and here's what I get when it is listed second:

I also attached these responses in a file in case they are easier to read in 
an editor.

I also discovered that my router keeps a log of network activity.  In the case 
that does work, it records 2 transactions with ichart.yahoo.com and then 2 
with finance.yahoo.com.  In the case that doesn't work, I get only the 2 
transactions with ichart.yahoo.com.

In response to the question from Rinaldi: I am not able to connect to port 53 
of the router using telnet, but I am able to connect to port 53 of my ISP -- 
the same experience as you reported.
