我最近将路由器换成了华为 EG8145V5，我需要连接到公司的 VPN 才能工作。当我使用以太网时，连接可以正常工作，但当我切换到 wifi 时，连接不起作用。
我的 VPN 配置是：
L2TP IPsec 选项已禁用
IPv4 和 IPv6 自动
这是我使用 wifi 连接到 VPN 时的系统日志

路由器 IP 配置
答案1
日志摘录：
Oct 13 08:05:21 pvqr pppd[7954]: local IP address 10.10.1.2
Oct 13 08:05:21 pvqr pppd[7954]: remote IP address 10.10.1.1
看起来10.10.1.0/24私有地址正在用于本地和远程地址。您能将华为 EG8145V5 配置为使用除 之外的其他地址10.10.1.0/24吗？
通过以太网连接，我认为只是侥幸没有与远程网络发生 IP 地址冲突。
