Hi all,

All the best

Hi my friend 

Initially there are 4  security services that offer IPSec VPN: Authenticacion, confidentiality, integrity data and replay detection. To implement these services there are two packet headers that are AH Authentication Header and ESP encapsulation Security Payload, this last is the most useful and secure. 

The ESP has two modes Tunnel and transport 

there are these different CISCO SOLUTIONS

Site-to-Site
IPsec VPN
Cisco
DMVPN
Cisco
GET-VPN
FlexVPN Remote
Access VPN

this theme is really long, i copy this link to check more information.

Hi,

I think you must ask this question on the Cisco Learning Community.  https://learningnetwork.cisco.com/s/

Read this port for basic knowledge:
