RtEthernetFilter

RtEthernetFilter can be used in conjunction with the RtTcpipServer and RtTcpipClient samples. RtEthernetFilter filters frames sent from machines running the client sample to a machine running the RTSSServer server. RtEthernetFilter does the following:

• Drops all receive and transmit ICMP packets from/to the hardcoded MAC address (0x00:0x0e:0x0c:0xc2:0x89:0x45).
• For each dropped received packet transmits an IP packet to a hard-coded destination MAC address (0x00:0x11:0x43:0x55:0x27:0x17) and source MAC address (0x00:0x15:0x17:0x37:0x12:0xdc).

To test the Ethernet filter, replace these hard-coded addresses with the desired addresses and rebuild the filter driver.

To use the RtEthernetFilter with a particular NIC driver, you must:

1. Configure and enable the filter using the eRTOS Control Panel.
2. Run the client sample with the t option on at least one machine.
