* Be more specific regarding the protocol in use for IPSec policies.Guilhem Moulin2015-06-071
| | | | We use ESP only, so other protocols shouldn't be ACCEPTed.
* Prohibit binding against the IP reserved for IPSec.Guilhem Moulin2015-06-071
| | | | | | | | | Packets originating from our (non-routable) $ipsec are marked; there is no xfrm lookup (i.e., no matching IPSec association), the packet will retain its mark and be null routed later on, thanks to ip rule add fwmark "$secmark" table 666 priority 666 ip route add blackhole default table 666
* Use a dedicated, non-routable, IPv4 for IPSec.Guilhem Moulin2015-06-072
| | | | | | | At the each IPSec end-point the traffic is DNAT'ed to / MASQUERADE'd from our dedicated IP after ESP decapsulation. Also, some IP tables ensure that alien (not coming from / going to the tunnel end-point) is dropped.
* Major refactoring of the firewall.Guilhem Moulin2015-06-071
| | | | | | | | | | Also, added some options: -f force: no confirmation asked -c check: check (dry-run) mode -v verbose: see the difference between old and new ruleset -4 IPv4 only -6 IPv6 only
* Configure v4 and v6 iptable rulesets.Guilhem Moulin2015-06-071
