kết xuất ở trên cho thấy không có vấn đề định tuyến là tốt.
nhưng tôi không thể giải quyết bất cứ điều gì:

ubuntu@ubuntu:~$ nslookup www.google.com 8.8.4.4

tcpdump cho thấy rằng các yêu cầu dns được gửi, nhưng chúng tôi không bao giờ thấy bất kỳ phản hồi nào cho các yêu cầu của chúng tôi:

Không có bộ lọc tại chỗ:
root@ubuntu:~# ufw status
Status: inactive
iptables không được cài đặt
Tôi không nghĩ đó là một vấn đề định tuyến, bởi vì ping đến một ip internet hoặc các ips dns (của vpn) trở lại bình thường.
Tôi đã kiểm tra syslog nhưng không tìm thấy bất kỳ nhật ký liên quan đến vpn.
Tôi đã thử một nhà cung cấp vpn miễn phí khác và có cùng một vấn đề.
Tôi đã đào đi tìm lại nhiều lần thông qua google nhưng không thể tìm thấy bất kỳ câu trả lời hay dẫn dắt nào. Nó bắt đầu trở nên nổi tiếng vào thời điểm này, bởi vì tôi bắt đầu làm các bài kiểm tra tương tự lặp đi lặp lại và không biết phải làm gì.
bài viết tôi đã đọc trong stackoverflow:
Không có internet trên kết nối OpenVPN -> giải pháp là đặt 'đẩy "tùy chọn dhcp DNS 8.8.8.8"' trong máy chủ conf. Đối với tôi, tùy chọn này xuất hiện trong đầu ra gỡ lỗi khi khởi động máy khách.
OpenVPN + iptables: không chuyển tiếp lưu lượng -> đó là sự cố liên quan đến máy chủ + quy tắc iptables.
(GIẢI QUYẾT) OpenVPN - Kết nối trình quản lý mạng Ubuntu ổn, nhưng không giải quyết, không ping, không có internet -> cái này có vẻ rất thú vị, nhưng vấn đề dns đã được giải quyết bằng lệnh dnsmasq trên vps.
/superuser/717383/vpn-dns-resolution -> Tôi nghĩ đây là vấn đề liên quan đến máy chủ.
Máy chủ OpenVPN không cung cấp quyền truy cập vào internet -> không có giải pháp nào được cung cấp, nhưng tôi đoán đây là một iptables (tùy chọn chuyển tiếp) hoặc vấn đề liên quan đến máy chủ.
Tôi đã gửi mail cho cả hai nhà cung cấp vpn nhưng không có câu trả lời sau hơn 2 ngày.
bất kỳ ý tưởng? cảm ơn mọi người rất nhiều
