If your computer is using a static IP address, then you can also consider changing to a different static IP address.
The current IP address may be conflicting with the set of IP addresses that the DHCP server is giving out.
To do this, click on Control Panel, go to icons view and then click on Network and Sharing Center.
On the left hand side, click on Change adapter settings.
Right-click on the network adapter that is currently being used for your Internet connection and then select Properties.
Click on Internet Protocol Version 4 (TCP/IPv4) and then click on the Properties button.
After running this command, you need to run the command to renew your IP address, which it will try to get from the DHCP server.
After a few seconds, you should see the results and there should be an IP address listed next to IPv4 Address.
You can set up a second private subnet, a different one, in the VPN Settings page in the Admin UI, in the section titled Static IP Address Network (optional).
Set up a unique subnet there and the Access Server will then have a subnet it can use for static IP address assignment.
