    VPN Connection Issues

    by wick100 ·

    I use a Kali Linux Virtual Machine to connect to a VPN for penetration testing. In April of this year I purchased an identical replacement laptop with different OS and more, faster SSD

    – Original: 14″ Lafite Pro, Windows 10 Pro 64 bit
    – New: 14″ Lafite Pro, Windows 10 Home 64 bit

    Since purchasing this new laptop I’ve had constant VPN connection issues with both VPN clients that I use (OpenVPN and ForticlientSSL VPN). The VPN connection is either interrupted or killed. Open VPN will successfully reconnect automatically around 80% of times, whereas Forticlient VPN requires a manual reconnection. The interruption/disconnection seems to occur when sending traffic, such as performing intense port scans; however, I’ve also witnessed many interruptions when no manually generated traffic is being sent. I am using the identical WiFi broadband connection that I used without issue on my previous laptop. Up/down speeds are around 16/1, and as noted, there were no previous issues. I have tried the following to fix the issue, unsuccessfully:

    1. Changed to mobile data hotspot with much faster data rates

    2. Changed the VPN connection mode of the VPN clients from UDP to TCP

    3. Changed the network adapter of the Virtual Machine from NAT to Bridged

    4. All combinations of 1, 2, & 3

    5. Updated all network adapter drivers on the host machine from within the device manager (suggested by someone)

    My limited network troubleshooting knowledge is now exhausted, and the only remaining option that I can think of is to reinstall Windows. Also, for my particular purposes I have to connect to the VPN via the Virtual Machine as opposed to the host system.

    Does anyone have any idea what could be causing this issue?

    Thanks
