Sorry. This is the problem I asked help for in my last thread called
"My Linksys WRT54GS router is losing its DNS configuration ..." in this
forum.
The problem was due to the fact that my ISP was doing what you called
"DNS juggling".
Alchemy can refresh the DNS addresses more frequently so my problem did
not happen anymore.

I am not familiar with Linux so I did not know this way of reading the
logs.
I was only reading the logs from the Alchemy Web interface.
Thanks for the tricks.

In facts, I want to switch off my computer firewall (which eat my CPU)
and let the router firewall work instead.
When something goes wrong (like someone doing a port scan or other bad
thing on my computer), ZoneAlarm (my firewall) gave me a lot of
information (like event time, DNS name, used port, number of tentatives
....)
I wanted to do the same with my router and the Web admin interface does
not give so much details.

I did not think of traffic analysis and did not know it was possible to
get information about it with this router/firmware.
That seems very interesting so I am going to have a look at your links.

You are perfectly right.


Thanks Jeff.
