How to Configure Site-to-Site VPN on Cisco Router
In order to configure a site-to-site VPN on a Cisco router, follow these steps:
Main Thought: Creating Extended ACL
Create an access-list and define the traffic that should pass through the VPN tunnel.
Main Thought: Create IPSec Transform (ISAKMP Phase 2 policy)
Create an IPSec Transform policy that specifies the encryption and authentication algorithms to be used for the VPN connection.
Main Thought: Create Crypto Map
Create a Crypto Map that ties together the access-list and IPSec Transform policy.
Main Thought: Apply Crypto Map To The Public Interface
Apply the Crypto Map to the public interface of the router to enable the VPN connection.
Key Points
1. Extended ACL
The access-list determines the traffic that will be allowed through the VPN tunnel.
2. IPSec Transform
The IPSec Transform policy specifies the encryption and authentication algorithms for the VPN connection.
3. Crypto Map
The Crypto Map ties together the access-list and IPSec Transform policy.
4. Applying the Crypto Map
Applying the Crypto Map to the public interface enables the VPN connection.

How does a Cisco site to site VPN work
A virtual private network (VPN) is a network connection that establishes a secure tunnel between remote peers using a public source, such as the Internet or other network. VPNs use tunnels to encapsulate data packets within normal IP packets for forwarding over IP-based networks.

What two methods can be used to configure VPNs on a Cisco router
The Cisco Easy VPN client feature can be configured in one of two modes—client mode or network extension mode. Client mode is the default configuration and allows only devices at the client site to access resources at the central site. Resources at the client site are unavailable to the central site.
What ports are required for site-to-site VPN
What kind of ports does a VPN usePoint-to-Point Tunneling Protocol (PPTP) — Port 1723 TCP.Layer Two Tunneling Protocol (L2TP) — Ports 1701 TCP, 500 UDP, and 4500 UDP.Internet Protocol Security (IPSec) — Ports 500 UDP and 4500 UDP.Secure Socket Tunneling Protocol (SSTP) — Port 443 TCP.
When should I configure a site-to-site VPN

What is the difference between VPN client and VPN site-to-site
Types of VPN connections
Client-to-Site (or Remote Access) and Site-to-Site (or Gateway-to-Gateway). The difference between them is simple: Client-to-Site VPN is characterized by single user connections. In contrast, Site-to-Site VPNs deal with remote connections between entire networks.
What is difference between site-to-site VPN and IPsec VPN
Site-to-Site VPN provides a site-to-site IPSec connection between your on-premises network and your virtual cloud network (VCN). The IPSec protocol suite encrypts IP traffic before the packets are transferred from the source to the destination and decrypts the traffic when it arrives.

Which IPsec mode is used for a site-to-site VPN
Tunnel mode
Transport mode is often between two devices that want to protect some insecure traffic (example: telnet traffic). Tunnel mode is typically used for site-to-site VPNs where we need to encapsulate the original IP packet since these are mostly private IP addresses and can't be routed on the Internet.
