PPP connection created by SonicWall NetExtender on Ubuntu 20.04

I'm trying to connect to the client VPN via Sonicwall NetExtender. On Windows there is no problem, but I cant't connect on my Linux Desktop (sometimes it works, but it's the exception).

When I connect everything seems to be ok, but the result is as if it's not connected. If I do a ip a on the console I can see the ppp0 connection created,

20: ppp0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1280 qdisc fq_codel state UNKNOWN group default qlen 3
    link/ppp 
    inet 192.168.200.200 peer 192.0.2.1/32 scope global ppp0
       valid_lft forever preferred_lft forever

Can I assume the problem is related to that 192.0.2.1/32? The provider IP is not that, but may be its local addreess. If it's so, how can I change the ipcp-accept-remote flag of the ppp connection created by the NetExtender client? Can I even change it after the connection is created?

Edit 19/07/21:

I've tried disabling NetworkManager with no effect. Then I've enabled debug logging of NM and got this:

PPPD trong suy nghĩ của tôi thường không phải là VPN .-) và tôi tin rằng bạn đã thiết lập VPN của mình một cách Wornly, vì tôi tin rằng 192.0.2.1 không thuộc sở hữu của bạn và imho không dành riêng cho việc sử dụng mạng LAN. thay đổi hoặc cập nhật nó thành 192.168 hoặc 172.16 hoặc 10.

Tôi đã thử một số điều khiển từ xa với `ifconfig ppp0 pointopoint XXX.XXX.2.1` và thậm chí cả IP công khai của nhà cung cấp nhưng tôi vẫn không có kết nối mạng. Thay đổi có thể yêu cầu một số cấu hình khác không? Thật không may, tôi không có quyền truy cập vào tệp cấu hình của ppp đã tạo do ứng dụng khách NetExtender đã định cấu hình nó một cách tự động. Tuy nhiên, tôi sẽ cố gắng hỏi một số đồng nghiệp về IP thực mà tôi cần. Cảm ơn.

Câu hỏi này là trong các ngôn ngữ khác:

Đăng câu trả lời

Hầu hết mọi người không hiểu rằng việc đặt nhiều câu hỏi sẽ mở ra cơ hội học hỏi và cải thiện mối quan hệ giữa các cá nhân. Ví dụ, trong các nghiên cứu của Alison, mặc dù mọi người có thể nhớ chính xác có bao nhiêu câu hỏi đã được đặt ra trong các cuộc trò chuyện của họ, nhưng họ không trực giác nhận ra mối liên hệ giữa câu hỏi và sự yêu thích. Qua bốn nghiên cứu, trong đó những người tham gia tự tham gia vào các cuộc trò chuyện hoặc đọc bản ghi lại các cuộc trò chuyện của người khác, mọi người có xu hướng không nhận ra rằng việc đặt câu hỏi sẽ ảnh hưởng—hoặc đã ảnh hưởng—mức độ thân thiện giữa những người đối thoại.
