Notes about WinPcap

In certain situations, a personal firewall (either Windows Firewall, or third party) on the PC may interfere with receiving responses back from ETH32 devices. Typically, this is only a problem when the ETH32 has not been properly configured with a valid IP for the network to which it is connected. While disabling the firewall is one solution, it may be desirable to use a "sniffer" to see the packets on the network before they get to the PC's firewall. WinPcap is a free and open-source sniffer library that provides this functionality. If WinPcap is installed on your PC, you can load this plugin in the ETH32 API to utilize the sniffing capability of WinPcap. There are a few items to be aware of:
