Just a question on IPSec that can be implemented through Group Policy, Manually, etc.
When it comes to creating Firewall rules with IPSec, im trying to understand how it is implemented within Windows. Does it create a IPSec tunnel between devices and encapsulate the original TCP/UDP Packet within a IPSec packet, or does it merely use IPSec encryption to encrypt the data portion of the packet and leave the standard TCP/UDP Headers on the packet.
Im trying to understand this so i can create the relevant firewall rules required to lock down my environment. Thx in advance!
