What is site to site VPN Cisco?

Site-to-Site IPSec VPN Tunnels are used to allow the secure transmission of data, voice and video between two sites (e.g offices or branches). ISAKMP, also called IKE (Internet Key Exchange), is the negotiation protocol that allows two hosts to agree on how to build an IPsec security association.

What is site to site configuration?

A site-to-site setup is where two (or more) different networks are connected together using one OpenVPN tunnel. In this connection model, devices in one network can reach devices in the other network, and vice versa. The implementation of this is, for as far as Access Server is involved in this, relatively simple.

What are the types of site to site VPN?

Types of Virtual Private Network (VPN) Protocols:

• Internet Protocol Security (IPSec): Internet Protocol Security, known as IPSec, is used to secure Internet communication across an IP network.
• Layer 2 Tunneling Protocol (L2TP):
• Point–to–Point Tunneling Protocol (PPTP):
• SSL and TLS:
• OpenVPN:
• Secure Shell (SSH):

What is VPN and site-to-site VPN configuration?

A site-to-site Virtual Private Network (VPN) provides this by creating an encrypted link between VPN gateways located at each of these sites. A site-to-site VPN tunnel encrypts traffic at one end and sends it to the other site over the public Internet where it is decrypted and routed on to its destination.

What is required for site-to-site VPN?

In order to set up an internet-based site-to-site VPN between two sites, a VPN gateway (router, firewall, VPN concentrator, or security appliance) such as the Cisco Adaptive Security Appliance (ASA) is required at both sites.

A Point-to-Site (P2S) VPN gateway connection lets you create a secure connection to your virtual network from an individual client computer. P2S VPN is also a useful solution to use instead of S2S VPN when you have only a few clients that need to connect to a VNet.

How do I create a site to site VPN?

1. Prerequisites.
2. Step 1: Create a customer gateway.
3. Step 2: Create a target gateway.
4. Step 3: Configure routing.
5. Step 4: Update your security group.
6. Step 5: Create a Site-to-Site VPN connection.

How do I know if site to site VPN is working?

To verify that your VPN tunnel is working properly, it is necessary to ping the IP address of a computer on the remote network. By pinging the remote network, you send data packets to the remote network and the remote network replies that it has received the data packets.

What is site to site VPN connectivity?

A site-to-site virtual private network (VPN) is a connection between two or more networks, such as a corporate network and a branch office network. With a site-to-site VPN, a company can securely connect its corporate network with its remote offices to communicate and share resources with them as a single network.

What does a site to site VPN do?

What is the Cisco ASA VPN terminator?

The Cisco ASA is often used as VPN terminator, supporting a variety of VPN types and protocols. In this tutorial, we are going to configure a site-to-site VPN using IKEv2. IKEv2 is the new standard for configuring IPSEC VPNs.

How is a VPN tunnel created between ASA1 and asa2?

As described in the topology scenario below, a VPN tunnel will be created between ASA1 and ASA2, connecting the two company sites, HQ and Branch1. Behind each security appliance there is a private LAN network.

What are the default tunnel groups in the ASA?

There are two default tunnel groups in the ASA: DefaultRAGroup is the default IPsec remote-access tunnel group and DefaultL2Lgroup is the default IPsec LAN-to-LAN tunnel group. – Connection type – IPsec LAN-to-LAN. – Authentication method for the IP – in this scenario we will use preshared key for IKEv2.

How to send traffic from ASA to stongswan?

This traffic needs to be encrypted and sent over an IKEv1 tunnel between ASA and stongSwan server. Both peers are going to authenticate each other using a Pre-shared-key (PSK).
