Apps that monitor port connections and attempted connections

[BTRY B 529th FA BN]

I am looking for an app that will tell the user when a port is being accessed. Incoming and Outgoing. I've been getting constant SYN Flood attacks. I'd like to just know what ports so I can block them at my modem level. Thanks

You can use Wireshark.

www.wireshark.org

This is a sniffing program that will tell you every attempt that is hitting your computers NIC, it will also show if you computer responds. You can also do a netstat to see what ports are listening on your computer and if they are currently connected.

If you have a Router the Router Blocks port access form the Modem in.

It allows only access to what you manually opened or to ports that the application that use use from the inside need in order to function.

You can not control the traffic on the Internet and signals hitting the Modem are outside traffic that is beyond your control, just like the traffic on the street.

I.e. you can lock the entrance to your house but you can control who is passing by the gate.

If your fear was evoked by looking at WAN side log of your Router, avoid looking at the log.

As for the LAN side of the Network, putting this free application on each computer would show you in real time which ports are used for Internet and LAN traffic.
