The package supports IP in IP by registering the ipip protocol handler Following options are configurable -peeraddr (IPv4 remote address) -ipaddr (IPv4 local address) -ttl (time to live of encapsulating packet) -tos (type of service of encapsulating packet either inherit (outer header inherits the value of the inner header) or hex value) -df (don't fragment flag of encapsulating packet) -mtu (IPIP tunnel mtu) -tunlink (bind tunnel to this interface) -zone (firewall zone to which the IPIP tunnel will be added) Signed-off-by: Hans Dedecker <dedeckeh@gmail.com> SVN-Revision: 42746master
