Por que 'ipsec statusall' não mostra nenhuma conexão?

  • 772

Finalmente consegui colocar um túnel entre meu computador (strongswan) e um Zyxel Zywall 110 funcionando.

Estou me conectando usando certificados e, a julgar pelos logs, a conexão VPN real parece ter sido estabelecida.

No entanto, embora a VPN pareça estar estabelecida, parece que a saída de ipsec statusallnão concorda.

Status of IKE charon daemon (strongSwan 5.1.2, Linux 3.19.0-33-generic, x86_64):

  10.0.3.1
  192.168.100.6
Connections:
Security Associations (0 up, 0 connecting):
  none

Por último, a saída de ip route showme dá o seguinte.

default via 192.168.43.1 dev wlan0  proto static 
10.0.3.0/24 dev lxcbr0  proto kernel  scope link  src 10.0.3.1 
192.168.43.0/24 dev wlan0  proto kernel  scope link  src 192.168.43.101  metric 9

A conexão VPN foi configurada com o Network Manager e estou usando certificados para estabelecer a conexão. Não consigo acessar nenhum recurso na rede com a qual estabeleci a conexão VPN.

Estou faltando alguma coisa na configuração? O que eu poderia estar perdendo?

vpn ipsec strongswan ubuntu-14.04

    O daemon IKE usado pelo plug-in NetworkManager ( charon-nm) é diferente do daemon IKE regular ( charon) com o qual você interage por meio do ipsecscript.

    Portanto, você não poderá ver o status das conexões estabelecidas por meio do plug-in NetworkManager, ipsec statusallpois isso mostrará apenas as conexões e SAs gerenciadas pelo daemon regular, que são configuradas em ipsec.conf.
