OpenWRT StrongSwan IPsec 客户端连接（‘用户’（我自己）的 XAuth 认证失败）

OpenWRT StrongSwan IPsec 客户端连接（‘用户’（我自己）的 XAuth 认证失败）

我正在尝试配置我的 OpenWRT 路由器以连接到远程 VPN 服务器。我拥有的凭据是正确的，但由于某种原因，连接无法在路由器上进行身份验证。以下是我的配置

/etc/ipsec.conf

conn l2tpconn
  keyexchange=ikev1
  authby=xauthpsk
  xauth=client
  left=%defaultroute
  leftsourceip=%config
  leftfirewall=yes
  leftauth=psk
  leftauth2=xauth
  leftid=user
  right=<server_ip>
  rightsubnet=0.0.0.0/0
  rightauth=psk
  rightauth2=xauth
  auto=add

/etc/ipsec.secrets

%any <server_ip> : PSK 'secret'
'user' : XAUTH 'password'

也许这是很简单的事情，而我却忽略了它，但如果你们有任何建议，那将非常有帮助。谢谢。

所以，我弄清楚了我的问题是什么，它是多种因素的结合。

  1. 我没有意识到服务器正在将 XAUTH 请求记录到 /var/log/auth.log 我以为它在 /var/log/syslog 中

  2. 阅读日志后，我注意到它正在检查 /etc/ipsec.d/passwd 中的凭据，而不是像我所想的那样在 /etc/ppp/chap-secrets 中检查凭据，无论出于什么原因。

然后，我将我的用户名和散列密码（openssl passwd -1“密码”）添加到 /etc/ipconf.d/passwd 并且成功了。
