Unable to connect to server from M1 Mac
Posted: Wed Jun 22, 2022 4:43 am
I am trying to set up remote access to my office.
I have installed SoftEther Server on a Windows 10 PC within the office LAN. On this PC I have:
- Created a virtual hub and it says that it is online.
- Added some users to the virtual hub.
- Set up a local bridge to connect the virtual hub to the PC's network adaptor.
- Configured the selected network adaptor to VLAN transparency.
- Enabled L2TP over IPsec.
- Disabled antivirus and turned off the Windows firewall on the server to ensure they are not interfering with the VPN.
In the router (Sagemcom brand), I have:
- Enabled port forwarding for TCP port 5555 (external) from all addresses to port 5555 on the IP address of the PC
- Enabled IPSEC which appears to forward TCP port 500:UDP port 4500.
I am then trying to establish a VPN connection using an M1 Mac. I am able to connect to other L2TP over IPSec VPN's, so I know this computer is able to do so. However, I always get the message "The LT2P-VPN server did not respond".
Troubleshooting steps I have taken:
- If I ping the DDNS hostname address provided by SoftEther it correctly resolves the public IP address of my router, so I know that I am attempting to connect to the correct address
- I have tried entering the IP address of the router instead of the DDNS hostname (same result)
- I have used TCPing to check that port 5555 is open at the DDNS host (router), and it reports that the port is open
But somehow the connection still cannot get through to the server on the PC.
What else can I try to diagnose this problem?
