Flexi-Chains enables you to create chains.
Each chain is composed of links.
Links are chronologically numbered integers i.e:
link 1, link 2, link 3, etc...
A link can be a guard or a tunnel.
A guard is intended to act as a dedicated guard - (e.g. firewall, IPS/IDS).
A tunnel is intended to tunnel/forward your traffic.
FLexi-chains enables you to chain together an unlimited^ number of links - of guards and/or tunnels.
Flexi-chains enables you to chain together any^^ tunnel protocol (openvpn, socks proxy, TOR, etc), in any order^^.
Although there is much overlap, to simplify things - you should think of guards and tunnels as entirely different from one-another.
Think of it like this:
| Link (1,2,3...) |
|---|
| Guard | Tunnel |
A guard link has a guardVM and
How this works
Simply add the tag guardVM to any of your QubesVMs
