CentOS IPsec: Não podemos nos identificar com um dos dois finais desta conexão [fechado]

Question

Eu tenho problema com o IPsec no centOS. Ao adicionar uma conexão usando

ipsec auto --add cx

Isso dá

multiple ip addresses, using  127.0.0.1 on venet0

Ao usar

ipsec auto --up cx

Recebo Não podemos nos identificar com nenhum dos dois lados dessa conexão.

saída ip addr
