Explenation of IPSec fields

[aljaz@iskratel.si (Aljaz Tomaz RDSI)]

Hi!
I just trace IPSec packets with SMS Network Monitor between 2 WinNT stations
with MSR IPv6 1.3 and I need some explenation. In ESP Trailer I have
following trace:
ESP trailer
	ESP Padding = 1 (0x1)
	ESP Pad Lenght = 2 (0x2)
	Next Header = 58
	etc

ESP Pad Lenght means that they are 2 byts of padding, where are this two
bytes (is one ESP Padding?, where is the other one).

Regards,
Tomaz
