Did you do anything involving firewalling rules? Perhaps you
installed a package, like ipmasq, that installs such rules for you?

Check your firewall rules lists:
/sbin/ipchains -n -L
If something (or you) has set up firewall rules before the dhcp-controlled
interface is configured, or reconfigured dynamically, then likely the
old rules may no longer match the new interface properties. This could be
the cause of the "Packet log: input DENY .." entries in your logs.

There is webmin, it appeared in unstable a little time ago. I don't
know how usable the debs are or how usable webmin in general is.
But these gui's will not help you find the source of problems any better
at all, quite the contrary in fact. By hiding the details, it makes it
much harder to know what is going on and to make a decent analysis.
