我正在運行帶有最新 OpenVpn 軟體包的 Ubuntu 20.04。第一次嘗試自行搭建VPN。
無法透過我的 Windows 電腦用戶端 ping 通目前位於 10.10.0.0 上的任何主機。
當 ssh 進入該子網路上的任何系統時，我可以 ping 任一方向。
UFW 目前已停用。
OpenVPN 連線正常，但我能夠 ping 通 openvpn 主機位址 10.10.3.98。
在所有系統上 /proc/sys/net/ipv4/ip_forward 設定為 1
考慮某種路線問題，但我嘗試了一些方法但沒有運氣。我需要集體。
謝謝你！

答案1
host2 沒有到達 的路線10.0.0.0/24。
10.0.0.0/24 via 10.10.3.98它需要一條知道的路線10.10.3.98作為到達的網關10.0.0.0/24。
請記住，您需要指向兩個方向的路線。
