Hello all,

1. I would like to ask if I use 3des-md5-96 for the authentication and
   encryption, how much extra info will be add to the original packet?

2. My tunnel mtu is 1420 and I got fragementation if I send 1400
   bytes UDP packets, the size of each packet is 1472 and 80. I can't do
   the math. Use 3des-md5-96 again. Can somebody explain why?

3. How come fragmentation occur since mtu is 1420 and 1400 is sended?

Thanks,

Pat
