Hi group,
Can anyone tell me the IP protocol/TCP port that the ISAKMP tunnel uses?
Also, does anyone know the sequence of events that take place between the
firewalls when a connection is being established? I am presuming that some
sort of negotation takes place between the firewalls before any encrypted
data is sent through (or this might be part of the stream I guess).
I am trying to find a way that I can identify a new encrypted connection
session being established between the firewalls when I put a sniffer on the
external interface on the firewall instigating the connection. Is there a
signature?
Many thanks,
Paul.
