I have a problem in an intranet and thought someone might have
encountered this allreads. I'm not too much a networks guy, so bear with
me if my description is missing precision:
two sites have to be isolated through a firewall, which are right now
fully connected and have probably many cross connections, e.g. users at
siteA using servers at siteB and vice versa.
Since most of these connections are historically grown and both sites
are very big just trying to interview people which connections they use
is probably not enough.
So I thought, let's just connect the sites through one cable or install
the firewall but let it open, and log all connections and get records
like
IpAtSiteA, port, protocol, direction, IpAtSiteB
Has anyone done this allready, or has anyone an idea how to do this
without logging all the connection data and post-process it? I need only
the fact that some connection has been up and which ip's, port and
protocol was involved, and only once per connection, e.g. if I found
some connection, I'm not interested in it anymore.
Thanks for any hints, Mathias
