Hi Everyone,
I'm planning to work remotely from my office, and I tried to turn on the SoftEther VPN service that I've had running. We've used this in the past quite effectively. Once we got it setup, it has worked well.
This time however, when I attempt to connect my client, it goes through the process and then immediately terminates the session.
I get something like this in the vpn server_log:
2022-05-16 08:53:19.726 L2TP PPP Session [1.146.152.113:1701]: Acquiring an IP address from the DHCP server failed. To accept a PPP session, you need to have a DHCP server. Make sure that a DHCP server is working normally in the Ethernet segment which the Virtual Hub belongs to. If you do not have a DHCP server, you can use the Virtual DHCP function of the SecureNAT on the Virtual Hub instead.
2022-05-16 08:53:29.648 L2TP PPP Session [1.146.152.113:1701]: The VPN Client sent a packet though an IP address of the VPN Client hasn't been determined.
2022-05-16 08:53:29.648 L2TP PPP Session [1.146.152.113:1701]: A PPP protocol error occurred, or the PPP session has been disconnected.
I tried turning on SecureNAT, but that seemed to create even more problems. How can I diagnose this issue?
