Annotation of embedaddon/strongswan/testing/tests/ikev2/rw-mark-in-out/description.txt, revision 1.1

1.1     ! misho       1: The roadwarriors <b>alice</b> and <b>venus</b> sitting behind the router <b>moon</b> set up
        !             2: tunnels to gateway <b>sun</b>. Since both roadwarriors possess the same 10.1.0.0/25 subnet,
        !             3: gateway <b>sun</b> uses Source NAT after ESP decryption to map these subnets to PH_IP_CAROL10
        !             4: and PH_IP_DAVE10, respectively.
        !             5: <p/>
        !             6: In order to differentiate between the tunnels to <b>alice</b> and <b>venus</b>, respectively,
        !             7: <b>XFRM marks</b> are defined for both the inbound and outbound IPsec SAs and policies using
        !             8: the <b>mark_in</b> and <b>mark_out</b> parameters in ipsec.conf.
        !             9: <p/>
        !            10: <b>iptables -t mangle</b> rules are then used in the PREROUTING chain to mark the traffic to
        !            11: and from <b>alice</b> and <b>venus</b>, respectively.
        !            12: <p/>
        !            13: The script designated by <b>leftupdown=/etc/mark_updown</b> automatically inserts
        !            14: iptables mangle rules that mark the inbound ESP packets as well as iptables IPsec-policy rules
        !            15: that let pass the tunneled traffic. In order to test the tunnel, the hosts <b>alice</b>
        !            16: and <b>venus</b> ping the client <b>bob</b> behind the gateway <b>sun</b>.
