Hi,

I think wireshark graphic dissection engine is showing a false error.
If you observer the attached file you can see an invalid length of IP Address.
Wireshark shows 17, but checking the packet-bytes window, we can see the value
of x20 (32 in decimal).

¿Did you catch my point?
¿Can you please help me?

Thanks,
Rui
