We have been using a VPN set up through Windows Server 2012 R2 Essentials for several weeks. The Essentials server (and 3 other Windows servers) run as virtual machines on VMware ESXi. Last night, we changed the virtual network adapters of our servers to try to resolve a problem with VMware crashing. Since changing the virtual adapters, everything has been working fine, except for the VPN.
The VPN shows as connected, but we are unable to ping or otherwise access internal resources. I have run the repair and reconfigured Anywhere Access using the wizard in the Essentials dashboard, but that has not resolved the issue. We can connect to Remote Web Access without problems. As I said, the VPN shows as connected and we get no error messages. All clients are Windows 8.1.
The IPv4 addresses are all the same, but the MAC address and possibly the IPv6 addresses have changed on our servers, if that makes a difference.
I’m not sure where to look or what to do at this point. Any suggestions?
