![]() ![]() However, not all networks support all protocols. Why is encapsulation useful?Īll packets use networking protocols - standardized ways of formatting data - to get to their destinations. The original packet itself becomes the payload. In an encapsulated packet, the header and payload of the first packet goes inside the payload section of the surrounding packet. A typical packet has two parts: the header, which indicates the packet's destination and which protocol it uses, and the payload, which is the packet's actual contents.Īn encapsulated packet is essentially a packet inside another packet. ![]() How does packet encapsulation work?ĭata traveling over a network is divided into packets. It can also set up efficient and secure connections between networks, enable the usage of unsupported network protocols, and in some cases allow users to bypass firewalls. Tunneling is often used in virtual private networks (VPNs). (Packets are small pieces of data that can be re-assembled at their destination into a larger file.) Tunneling works by encapsulating packets: wrapping packets inside of other packets. Similarly, in networking, tunnels are a method for transporting data across a network using protocols that are not supported by that network. In the physical world, tunneling is a way to cross terrain or boundaries that could not normally be crossed.

I rather have a vpn server act as the portal to my network as it has security as the primary as focus, more so even than ssh. And other protection like automatically incressing the retry times by (temporary) locking accounts. You would have to make sure that any accounts that can be connected to must use ssh passphrases only and accept no longer passwords to make sure only you can connect to protect against password hammering. In your case however it opens up ssh to the internet (even if you'd obfuscate it a bit by running it on another port on the outside and then forward it to the system running the sshd service). Used it for example to get to the cloud, with 3 or 4 jumphosts in between. You can then send all traffic through as many in between systems also running sshd to your own laptop or pc or whatever that is initiating the 1st step in the tunnel. Security officers don't like the idea in corporate environments because it allows for traffic that no-one can see as it is all tunneled but is really great if you don't have systems in between that can run a graphical interface to run an gui application. Works great in environments where there is no other option to make use of services except for ssh. Then you'd setup a ssh tunnel from cliwnt end (so needs a ssh client) and then send all traffic that needs to reach a system or service in your home network through that tunnel. Effectively you'd be needing to portforward ssh towards a system in your network.
