From: Rob Although there is more abstract software to manage firewalls, like ufw on debian-based systems and firewall-cmd on redhat systems, Iptables will help you understand what actually happens during filtering, mangling or routing a package. https://www.frozentux.net/iptables-tutorial/iptables-tutorial.html has a structured approach in explaining what happends when a package hits the firewall. Pay extra attention to Network Address Translation. Here is another nice HOWTO: https://netfilter.org/documentation/HOWTO/NAT-HOWTO-5.html

Tinc is a VPN daemon which tunnels IP packets and Ethernet frames over UDP. More on Tinc can be found on: http://tinc-vpn.org Here I will show a tinc setup with an alpha (as a listening peer) and a beta (a peer connecting to alpha). After setting up the VPN, alpha will be the gateway for beta. All traffic from beta will be routed through alpha and back. I will basically retell the man page documentation: https://tinc-vpn.org/documentation-1.1/tinc.conf.5 but in a more tutorial kind of way. diff --git a/tunneling.html b/tunneling.html index bc41648..ac68a7a 100644 --- a/tunneling.html +++ b/tunneling.html @@ -2,9 +2,9 @@ "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
