I am trying to build a packet with extension headers. With the packet builder it is not possible to assemble such a packet. As a solution I changed the packet with a hex-editor and added two extension headers. Now I am trying to play the packet with packetplayer, but the player does not send anything. With one extension header it works, when I add more extension headers it doesn't work anymore. Also packet builder does not recognise the extension header. Is there a solution for this problem, or am I doing something wrong?
