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.
