Hi,

I have 2 questions. I have done a google for the answers but nothing is forthcoming. I am hoping that this is a simple question that has come up elsewhere. If you would be so kind as to point me to those threads, I'd appreciate.

1 - Ethereal 0.9.15 is not decoding both of the STUN exchanges. our product sends out a STUN packet from local port x to gw port x. Then it sends out another STUN packet from local port y to gw port x. Ethereal is decoding only the first interaction. The second interaction is showing as only UDP. I can, of course, 'decode as...' but I'm not sure why I have to.

2- Ethernet has 14 bytes of header and then a 4 byte footer, yes? Why does Ethereal show the ethernet header as only 14 bytes? I can't find the other 4 bytes but they must be there.

I hope that these questions are not too dense. Any constructive pointers will be appreciated.
