[BUG] 无法同时启动多个OpenVPN

[MicroOps-cn]

因工作原因，需要接入到多个VPN环境，
如果使用相同的虚拟网卡模式(如都用TAP)，那么启动一个VPN连接的时候时候，其他使用TAP网卡的VPN，都会断开。
但是我使用NetworkManager(nmtui)来启动VPN, 其他VPN不会断开。

[justforlxz]

DDE 使用的就是 network manager，既然nmtui可以，那么控制中心应该也是可以的，我尝试一下。

[MicroOps-cn]

我使用nmtui可以同时连接了我所有的VPN,

但是当我尝试使用控制中心去连接VPN时，会随机断开其他的一个VPN

[MicroOps-cn]

DDE 使用的就是 network manager，既然nmtui可以，那么控制中心应该也是可以的，我尝试一下。

我猜测会不会是为了兼容其他类型VPN, 在连接前需要断开其他VPN连接

[MicroOps-cn]

这个问题什么时候能修复呢？

[BLumia]

这个应该算新需求吧，虽然原理上应该是可以支持的，但目前应该没做这样的支持以及相关的测试。 cc @meiyixiang

嗯，希望能尽快支持，
