 在某些情况下，你可能希望 VPN 客户端仅使用指定的 DNS 服务器来解析内部域名，并使用其本地配置的 DNS 服务器来解析所有其他域名。这可以使用 `modecfgdomains` 选项进行配置，例如 `modecfgdomains="internal.example.com, home"`。对于 IKEv2，将此选项添加到 `/etc/ipsec.d/ikev2.conf` 中的 `conn ikev2-cp` 小节。对于 IPsec/XAuth ("Cisco IPsec")，将此选项添加到 `/etc/ipsec.conf` 中的 `conn xauth-psk` 小节。然后运行 `service ipsec restart`。IPsec/L2TP 模式不支持此选项。

 In certain circumstances, you may want VPN clients to use the specified DNS server(s) only for resolving internal domain name(s), and use their locally configured DNS servers to resolve all other domain names. This can be configured using the `modecfgdomains` option, e.g. `modecfgdomains="internal.example.com, home"`. Add this option to section `conn ikev2-cp` in `/etc/ipsec.d/ikev2.conf` for IKEv2, and to section `conn xauth-psk` in `/etc/ipsec.conf` for IPsec/XAuth ("Cisco IPsec"). Then run `service ipsec restart`. IPsec/L2TP mode does not support this option.
