I made the racoon configuration in this topology
And I set up the racoon of the left server and the right server.
Left server /etc/racoon/racoon.conf configuration:
remote 1001::2 {
exchange_mode main,aggressive;
proposal {
encryption_algorithm 3des;
hash_algorithm sha1;
authentication_method pre_shared_key;
dh_group 2;
}
# generate_policy off;
}
#
sainfo address 2001:123::/64[any] any address 2002:123::/64[any] any {
pfs_group 2;
encryption_algorithm 3des;
authentication_algorithm hmac_md5;
compression_algorithm deflate;
}
left servner /etc/racoon/psk.txt configuration:
1001::2 P@ssworD
Left server /etc/ipsec-tools.conf configuration:
flush;
spdflush;
## Some sample SPDs for use racoon
#
spdadd 2001:123::/64 2002:123::/64 any -P out ipsec
esp/tunnel/1001::1-1001::2/require;
#
spdadd 2002:123::/64 2001:123::/64 any -P in ipsec
esp/tunnel/1001::2-1001::1/require;
The right server also sets the IP address differently, and following error is displayed.

How can I send an 2001:123::/64 computer's ICMP6 to 2002:123::/64 computer?
