Настройка pptp туннеля до tunnelbroker.net

Настраиваю ipv6 по схеме, предложенной на форуме: http://www.tunnelbroker.net/forums/index.php?topic=951.msg5424#msg5424

net.ppp2 подключается, пинги до конца тоннеля идут, а вот до сервера нет, хотя через интернет пинг есть.
net.he вообще не подключается и пишет про проблему с синтаксисом:

# /etc/init.d/net.he start
 * Caching service dependencies ...                                                      [ ok ]
 * Starting he
 *   Creating tunnel he ...
Usage: ip tunnel { add | change | del | show | prl } [ NAME ]
          [ mode { ipip | gre | sit | isatap } ] [ remote ADDR ] [ local ADDR ]
          [ [i|o]seq ] [ [i|o]key KEY ] [ [i|o]csum ]
          [ prl-default ADDR ] [ prl-nodefault ADDR ] [ prl-delete ADDR ]
          [ ttl TTL ] [ tos TOS ] [ [no]pmtudisc ] [ dev PHYS_DEV ]

Where: NAME := STRING
       ADDR := { IP_ADDRESS | any }
       TOS  := { NUMBER | inherit }
       TTL  := { 1..255 | inherit }
       KEY  := { DOTTED_QUAD | NUMBER }
