Cisco anyconnect how does it work

Anyconnect creates a tunnel interface with the IP received from the VPN gateway and sets up a default route for all packets to be routed to the tunnel interface. But how does the clients packets routed to the tunnel interface plumbed to the TLS session? In the case of Linux client, is it done using Linux kernel networking features or its implemented in the user space?

Manohar Your statement about the default route is not accurate. You CAN tunnel all traffic but you can also do what is called "split-tunnel" where only traffic for the subnets "advertised" over the tunnel are sent through it while then using the user's internet connection for the rest of the traffic. For example, browsing the internet would use your internet connection rather than the internet connection on the ASA at your office.

I don't know the answer to the question about whether this is done in kernel or user space. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Unfortunately Cisco AnyConnect does not feature any diagnostics, visibility or analytics functionality, leaving remote workers at the mercy of their own ability to troubleshoot IT issues.

Cisco AnyConnect is in widespread use and is frequently bundled alongside other Cisco deployments. All kinds of companies get great value from their AnyConnect investments, and it will continue to be a reliable, straightforward choice for many. The reality today, however, is that most workplaces have changed dramatically since this technology was first designed. A growing volume of organizations are instead turning to mobile-first software solutions that offer a better experience, richer analytics and a more robust policy engine.

NetMotion has become the premier choice in the VPN market, with hundreds of its customers making the switch from other solutions as remote and mobile working become increasingly important.

It today supports over organizations and one million workers that cannot afford to compromise when it comes to user experience, including 7 of the top 10 largest airlines and powers three quarters of first responders in North America.

When to choose AnyConnect Cisco AnyConnect is ideal for well-resourced IT teams with existing Cisco hardware, operating in environments unlikely to change for the foreseeable future.

When to choose something better Cisco AnyConnect is poorly suited for organizations with limited IT management resource, especially those that require simpler, swifter deployments and have unpredictable scaling requirements.

In these instances, leaders should look for a software-based VPN solution instead. When to choose AnyConnect Cisco AnyConnect is a solid choice for organizations with workers operating in fixed environments on reliable networks and where employee experience is a low priority. When to choose something better Cisco AnyConnect is not recommended for environments in which network performance is unstable, slow or unpredictable.

It also actively degrades the user experience, making it unsuitable for industries with high value employees or a mission-critical remote workforce. In these instances, leaders should look for a mobile-first, optimized VPN that improves the employee experience. What is a VPN "tunnel"? You may also like: What is a VPN? How to setup a VPN. Spread of threats from remote computers Remote access is a major threat vector to network security. Split tunneling Split tunneling occurs when a device on the remote end of a VPN tunnel simultaneously exchanges network traffic with both the public and private networks without first placing all the network traffic inside the VPN tunnel.

Here is a quick overview of the three main types of topologies: Hub-and-spoke In this VPN topology, multiple remote devices spokes communicate securely with a central device hub. A separate, secure tunnel extends between the hub and each spoke.

Point-to-point Establishing this topology requires specifying two endpoints as peer devices that will communicate directly with each other. Either device can initiate the connection. Full mesh In this topology, which works well in complicated networks, every device in the network can communicate with every other device via a unique IPsec tunnel. Implicitly supported topologies The three main VPN topologies also can be combined to create more complex topologies, including: Partial mesh This is a network in which some devices are organized in a full mesh topology, and other devices form either a hub-and-spoke or a point-to-point connection to some of the fully meshed devices.

Tiered hub-and-spoke This is a network of hub-and-spoke topologies in which a device can behave as a hub in one or more topologies and a spoke in other topologies. Traffic is permitted from spoke groups to their most immediate hub. Joined hub-and-spoke This is a combination of two topologies hub-and-spoke, point-to-point, or full mesh that connect to form a point-to-point tunnel. Be mindful of IPsec policy constraints An IPsec policy defines the characteristics of the site-to-site VPN, such as the security protocols and algorithms used to secure traffic in an IPsec tunnel.
