Hello I only can ping my own IP! I use the Heartbeat Client. The Configurtation: # Dynamic tunnels require the use of special configuration tools. # Configuration for SixXS Heartbeat Client # SixXS - http://www.sixxs.net # Autogenerated by SixXS Website (http://www.sixxs.net) # Created at 2004-03-03 17:06:20 # # Commentlines start with semicolon (;), hash (#), # double slash (//) or a space ( ). # Empty lines are ignored. # Argument values may be quoted using single (\') and double (") quotes. # # examples: # os linux # os "linux" # os \'linux\' # Operating System (linux/freebsd/openbsd/netbsd/winxp) os "linux" # Interface the tunnel should go over # used for detecting the local IPv4 endpoint ipv4_interface "ppp0" # IPv4 address of the POP (nlams01/nlams02/nlams04/demun01/iedub01/dkcop01) # This is also the address to where heartbeats are sent ipv4_pop "demuc01.sixxs.net" # ipv4_local is figured out automatically # from the ipv4_interface # Special case for people having their # endpoint behind a NAT #hb_behindnat 1 # # Don't change the local tunnel endpoint #hb_statictunnel 1 # # The hostname or IP of the 'external' IP # from which the heartbeat should originate #ipv4_local_resolve public-ip.example.net # Interface to be used for the tunnel # will be created on the OS's that need that ipv6_interface "sixxs" # The local and remote sides of the tunnel ipv6_pop "2001:6f8:900:16e::1" ipv6_local "2001:6f8:900:16e::2" # The prefix length of the tunnel # Tunnel space is thus ipv6_pop/ipv6_prefixlen ipv6_prefixlen 64 # The Heartbeat password for this tunnel hb_password "XXXXXXXXXXXXX" # The interval at which to send the heartbeat hb_sendinterval 60 # Informational: after this timeout the tunnel # is taken down at the POP side hb_timeout 300 # Put the client in the background?
