Filter udp destination port 53 (DNS) in both the LAN and PPP and compare.
	hint: udp.dstport==53
analyze if dns requests are being correctly resolved.


As you are using this commands:
	$ wget www.google.com
	$ wget www.livecdlist.com
which both work on port 80, filter the destination port 80 and compare.
	hint: tcp.dstport==80

Are the lists of packets any different between the lenny and squeeze setups?


If you have no experience with packet analysis, it would be very difficult 
to explain it all in this list. Sorry.
