Multiple VPN hubs, adapters and connctions

Post by pgitsov » Mon Feb 26, 2018 7:40 am

On a Windows Server 2012 R2 I have configured a VPN server with multiple VPN hubs (see attachment). A separate virtual adapter connects to each hub via a startup connection. Problem is that on Windows restart the first 14-15 connections manage to re-connect automatically while the rest report an error (Code 2) and keep re-connecting. In VPN Server Manager on a click on Connect-button I get an error "Protocol error occurred. Error was returned from the destination server." and the connection fails. After an hour the errors stop occurring, the pending connections get connected and Server Manager can connect to the server. Please help solve this, I am on ver. 4.22, Build 9634.

Could you check log of VPN server?
I think your connection is determined to be a DoS attack.
