I am using Pcap.net to try and establish a TCP client/server connection with c# code. I have a packet built and can send out a SYN, but the particular server I am trying to connect with needs extra 2 bytes of padding on the Ethernet layer. From all the Pcap.net documentation I haven't been able to find a away to add padding to that layer before I submit it to the packet builder. If anyone has any information on how I might achieve this, I would greatly appreciate it.
The two wireshark screen grabs illustrate the packet that gets accepted by the server (with padding), and the one that doesn't(no padding) respectively
The padding is added implicitly when you send the packet over the wire.
