A client VPN is best suited for businesses with remote employees who need to access company resources from afar. This type of VPN creates a secure tunnel between the user’s device and the company network, allowing them to safely access sensitive data and applications. The downside of a client VPN is that it requires each user to set up and manage their own connection, which can be time-consuming and difficult for IT departments to troubleshoot.
A site-to-site VPN, on the other hand, connects entire networks to each other over the internet. This allows businesses with multiple locations to share data and applications securely between all of their sites. Site-to-site VPNs are typically easier to set up than client VPNS, but they require more bandwidth and can be more expensive.
The main difference between these two types of VPNs is that site-to-site connections are permanent, while remote access connections are temporary. With a site-to-site connection, data is encrypted and sent through a dedicated tunnel between two locations. A remote access connection uses an existing public network, such as the Internet, to create a secure “tunnel” into the internal network.
Another difference between these two types of VPNs is that site-to-site connections require special hardware or software at both ends of the connection, while remote access connections can be made using any computer with an Internet connection.
Worth knowing
Cisco offers a wide variety of solutions for site-to-site VPNs, depending on your needs. For example, the Cisco RV325 Dual Gigabit WAN VPN Router offers an affordable, high-performance option for small businesses that need up to 50 IPsec tunnels and 9 PPTP/L2TP tunnels for secure connectivity. The Cisco ASA5505 Firewall Edition Bundle combines an industry-leading firewall with an IPSec VPN gateway in one easy-to-deploy unit, providing cost-effective protection and performance for small business and remote office/branch office (ROBO) environments.
For larger organizations with more complex networking requirements, Cisco also offers the Unified Communications Manager Business Edition (CUCM BE), which includes an integrated site-to–site VoIP gateway along with VoIP phone support and other features. The CUCM BE can be deployed as either a hardware appliance or in a virtual machine environment.
Worth knowing
First, you must connect to your Cisco RV042 VPN gateway. Then, select the “VPN” and “Gateway to Gateway” tabs.
Next, you will need to configure the following settings:
– The local security group is the subnet that will be reached by the VPN client.
– The remote security group is the subnet that will be allowed to communicate with the local security group.
– The IKE pre-shared key is a shared secret that is used to authenticate the IPsec peers.
– The phase 1 proposal is the encryption and authentication algorithms that will be used during phase 1 of the IKE negotiation.
– The phase 2 proposal is the encryption and authentication algorithms that will be used during phase 2 of the IKE negotiation.
Once you have completed these steps, you will have successfully configured a site-to-site VPN using a Cisco RV042 VPN router.
Worth knowing
Before we start, there are a few things we need to check off our list:
– Make sure both devices (the one acting as server and the one acting as client) have valid public IP addresses and can reach each other over the internet. If not, you may need to configure NAT (Network Address Translation) on your router(s).
– Install StrongSwan on both devices. On Debian or Ubuntu, this is as simple as running `sudo apt install strongswan`. For Fedora or RHEL/CentOS, use `sudo dnf install strongswan`.
– Generate RSA key pairs on both devices. We’ll use these later to authenticate our connection.
With that out of the way, let’s begin!
## Configuring the Server ##
We’ll start by configuring our server. Edit `/etc/ipsec.conf` and add the following lines:
“` conn myvpn # unique name for this configuration
left=10.0.0.1 # local IP address – replace with your own! right=10.1.1%); # remote IP address – replace with your own!
leftid=@myvpnserver # local identity string for authentication leftrsasigkey=/etc/ipsec# path to local RSA key pairpolicies=psk+updown; :wq “`
Now open up `/etc/strongswan/*`, which contains all of StrongSwan’s configuration files related to authentication methods, secrets, certificates, etc., and create a new file called `secret_psk`. Enter in a pre-shared key (PSK) that will be used to authenticate our connection later: sudo nano /etc/strongswan/# Secrets used by ipsec auto –add connectionsval myvpn PSK “supersecretkey123″Now all that’s left is to fire upStrongSwan! You can do this by runningsystemctl start strongswanand then verifying it’s running correctly withsystemctl status strongswanIf everything looks good, then moveon to setting up your client device.# Configuring the ClientFor our client device, we again needto edit `/etc/ipsec.*`, but this time weneed only add one line at the very bottom:conn myvpnAnd that’s it! Just like that, you’vesuccessfully configured a site-to-siteIPsec VPN using StrongSwanList any steps needed to complete taskChecklist:- [ ] Read over guideso you understand whatyou’re doing(trust me it helps!)https://wikiHow Illegal To Download Torrents? website.- [x] Gather equipment.- [x] Check equipment compatibilityif necessary.- [x] Place equipment in desiredlocation.- [ ] Follow instructions carefullyto avoid messing anything up.”);
