strongSwan - nenhuma configuração correspondente foi encontrada

Question

Estou tentando configurar o strongSwan para configurar um iPhone, mas estou recebendo um erro que tenho problemas para superar.

não foi encontrada nenhuma configuração correspondente de pares

O log de depuração completo é o seguinte:

Em ipsec.secrets eu tenho:

vpn-test.nimblex.net : RSA "/etc/ipsec.d/private/vpn-server-key.pem"

    

Answer 1

11[CFG]   id '%any' not confirmed by certificate, defaulting to 'C=US, O=NimbleX VPN Server, CN=vpn-test.nimblex.net'

Como você pode ver, sua identidade local é padronizada para o DN do assunto do certificado. No entanto, o par propõe vpn-test.nimblex.net como identidade, mas nenhuma configuração é encontrada:

14[CFG] looking for peer configs matching 172.31.9.29[vpn-test.nimblex.net]...82.137.12.236[10.140.156.120]

Portanto, altere a identidade esperada no par para o DN do assunto ou defina leftid=vpn-test.nimblex.net , que só funciona, no entanto, se esse FQDN estiver contido em uma extensão subjectAlternativeName no certificado do servidor.
