 Hello
 
 
 I've just tried the patch in this PR and found it not to work (yet).
 
 The keep-alive packets that are sent for IPv6 have their tcp port octets
 in the wrong order. Eg. if a dynamic rule exists for a connetion to port
 4000 (0x0FA0), the keepalives are sent to 40975 (0xA00F)
 
 I haven't looked into where this difference between ipv4 and ipv6
 originates, but forcing the byte-swap in send_pkt() makes everything work.
 I'd post the change I made, but I'm fairly sertain it's The Wrong Way (tm)
 to fix this.
 
 
 
 Greetings
 
 Joost.
