Depending on your VPN client you might be able to automatically select one VPN or the other depending on the network address of the local segment. Observe that all mentioning of NAT in this context denotes a NAT function which so to speak takes place within the tunnel perspective.
Connect a VNet to another VNet using an Azure VPN Gateway Step 1 - Plan your IP address ranges In the following steps, you create two virtual networks along with their respective gateway subnets and configurations. You then create a VPN connection between the two VNets. It’s important to plan the IP address ranges for your network configuration. Site To Site VPN Routing Explained In Detail | OpenVPN 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. How Virtual Private Networks Work - Cisco Oct 13, 2008
Linksys Official Support - Setting up a VPN Tunnel on two
Hi Folks, I am trying to establish routing between two Site to Site vpn tunnels, both of which are terminating on the same outside interface of my Cisco ASA. Please find attached Network Diagram for the same. All Firewalls used are Cisco ASA 5520. Both VPN tunnels between Point A and P We have two types of IPSEC VPNs: Lan-to-Lan (or site-to-site) encrypted VPN and Remote Access VPN. The first one is extensively used to securely connect distant office networks and the second one for allowing remote users/teleworkers to access resources on a central site network. Private Network (VPN), also called a gateway-to-gateway VPN. A VPN creates a secure tunnel between two sites via the Internet. For example, users at your branch offices can access file servers at the main office. All data is encapsulated so that your confidential information is protected as your users send and receive data. Configure the VPN connectivity between two Azure virtual networks It can also be used to learn configuring site-to-site VPN connection. 05-12-2015 09 min, 01 sec
Establish VPNs between sites. Then enable a dynamic routing protocol to share network information between the sites. In my experience, the routers will have some kind of virtual Point-to-Point link between them, perhaps a GRE tunnel or L2TP. The dynamic routing protocols treat this link like any other interface.
How a VPN works. A VPN uses a special protocol to establish a virtual channel between two machines or two networks. Imagine if you could blow a soap bubble in the shape of a tube and only you and your friend could talk through it.
