我有两个 VPN 服务器（Wireguard 和 OpenVpn），我的目标是连接到这两个服务器的客户端应该能够在它们之间进行通信。假设笔记本电脑 A 连接到 wireguard VPN 服务器，笔记本电脑 B 连接到 OpenVpn，我应该能够从 A 到 B 进行远程桌面/ping 等。如果 A 和 B 都连接到 wireguard 或 openvpn 服务器，它们就能够正常通信以进行远程桌面/ssh/ping 等。
这些服务器是 ubuntu 20 服务器，我可以毫无问题地互相 ping 通。
设置如下：
Wireguard：
Public IP: 1.2.3.4
Native IP: 10.0.0.235
Wireguard Server IP: 10.36.135.1
Wireguard Client IP: 10.36.135.2 onwards.
OpenVPN：
Public IP: 4.3.2.1
Native IP: 10.0.0.21
OpenVPN Server IP: 10.187.86.1
OpenVPN Client IP: 10.187.86.1 onwards.
每个客户端使用服务器的公共 IP 连接到 VPN 服务器并获取 VPN 客户端 IP 地址。例如，
笔记本电脑A：
Wireguard VPN IP：10.36.135.2
笔记本电脑B：
OpenVPN IP：10.187.86.2
我可以从每个客户端 ping 两个服务器 10.0.0.XXX，没有任何问题。但是，我无法从 10.187.86.2 ping 10.36.135.2。
我想我可能需要在每台服务器上添加一条路由，以便它们可以互相通信，但不确定要添加什么路由。
我已经捕获了每个服务器的一些信息。
