Hi, a) how do i create an ip6 in ip6 tunnel? debian iproute pkg 20010824-11 simulacron:~# ip tunnel add ip6sec0 mode ipip remote fe80::202:ddff:fe32:6525 local fe80::209:5bff:fe2f:ea7e Error: an IP address is expected rather than "fe80::202:ddff:fe32:6525" same with mode "gre" or "sit" -> it does not accept v6 addresses. Do I need some special or updated tool? b) using setkey I configured: spdadd 192.168.1.10 192.168.1.1 4 -P out ipsec esp/transport//require; spdadd 192.168.1.1 192.168.1.10 4 -P in ipsec esp/transport//require; as soon as the tunnel is created: ip tunnel add ip4sec0 mode ipip \ local 192.168.1.10 remote 192.168.1.1 racoon tries to contact the other host. why is that? no data should have passed the link so far. (maybe some ipv6 issue? pathmtu? nopmtodisc didn't help. ) also "ip tunnel" blocks till racoon times out, which is not wanted.
