Thomas Leonard 2002126b8b Rationalised firewall rules syntax 
Added explicit NAT target, allowing NAT even within client net and
making it clear that NAT is used externally.

Changed Redirect_to_netvm to NAT_to, and allow specifying any target
host.

README.md

qubes-mirage-firewall

An experimental unikernel that can run as a QubesOS ProxyVM, replacing sys-firewall. It uses the mirage-qubes library to implement the Qubes protocols.

Note: This firewall ignores the rules set in the Qubes GUI. See rules.ml for the actual policy.

To build:

$ opam install mirage
$ opam pin add mirage-clock-xen https://github.com/mirage/mirage-clock.git
$ opam pin add mirage-net-xen 'https://github.com/talex5/mirage-net-xen.git#disconnect'
$ opam pin add tcpip https://github.com/mirage/mirage-tcpip.git
$ opam pin add mirage-xen 'https://github.com/talex5/mirage-platform.git#mm'
$ opam pin add mirage-qubes https://github.com/talex5/mirage-qubes.git
$ opam pin add mirage-nat 'https://github.com/talex5/mirage-nat.git#simplify-checksum'
$ mirage configure --xen
$ make

You can use this with the test-mirage scripts to deploy the unikernel (mir-qubes-firewall.xen) from your development AppVM. e.g.

$ test-mirage mir-firewall.xen mirage-firewall
