You can see the packages to pass, but you can not see its contents IPSec Packet Types IPSec packet types include the authentication header (AH) for data integrity and the encapsulating security payload (ESP) for data confidentiality and integrity. The authentication header (AH) protocol creates an envelope that provides integrity, data origin identification and protection against replay attacks. It authenticates every packet as a defense against session-stealing attacks. Although the IP header itself is outside the AH header, AH also provides limited verification of it by not allowing changes to the IP header after packet creation (note that this usually precludes the use of AH in NAT environments, which modify packet headers at the point of NAT). AH packets use IP protocol 51. The encapsulating security payload (ESP) protocol provides the features of AH (except for IP header authentication), plus encryption. It can also be used in a null encryption mode that provides the AH protection against replay attacks and other such attacks, without encryption or IP header authentication. This can allow for achieving some of the benefits of IPSec in a NAT environment that would not ordinarily work well with IPSec. ESP packets use IP protocol 50.
To test the IPSec policies, use IPSec Monitor. IPSec Monitor (Ipsecmon.exe) provides information about which IPSec policy is active and whether a secure channel between computers is established.
Yes, VPN uses IPSec to encrypt the contents of the packet in one of two ways. The packet is encrypted and then placed in another packet for transport, with tunnel encryption the entire packet is encrypted including the header is placed in the public network packet.

Java doesn't use header files.
stdbool header file use for a new data type that is boolean value
You can only use an authentication key to make one account, but you can use the disk to download the game on as many computers as you want.
the use of header files is to add functionality. Header files are basically saying put code in that header file here so you don't have to type that many lines of code.
in the java as we use the inheritance property in the same way we can get the the inheritance property in c by using the prepared header files( .h files). there a single program in c use the many methods of many header files like math.h give us to use the use of floor(), sqrt() e.t.c. functions..
