Now that I have a new wireless access point that has no filtering on board,
I added iptables rules for the relevant interface on my server.
My ADSL modem and the a/p are on one segment that connects to my server
on a dedicated interface. The new rules manage this interface.
My internal machines are on a separate interface on the same server, and
have no restrictions.
I noticed that from time to time I get dropped packets arrving from the 'net
that I do not expect. They seem to be from *.ytimg.com:443.
I do have the usual RELATED,ESTABLISHED rule which is supposed to manage
those so why is this not caught (ACCCEPT'ed)?
I think that these are packets belonging to a youtube I was watching,
which I just closed and it arrived after that action. If so then it is
correct to DROP them.
Is my understanding correct?
