Hi all,
Having a real tough time getting Windows 7 machines connect to my Draytek Vigor 3900 VPN.
I know it's not an issue with blocked ports or firewall issues as all of the computers using W10 connect to the VPN no problem however W7 machines can never connect.
I connect by using the Draytek Smart VPN client which also does the registry changes. It hangs on dialing for about 60 seconds then just says 'Unknown Error'
If I try to use the inbuilt W7 VPN, I have no luck at all and get given error 809
I can use the exact same config and same user on a W7 machine and it just wont connect at all
I have added/modified the 'AssumeUDPEncapsulationOnSendRule', 'ProhibitpSec' and 'AllowL2TPWeakCrypto' registries.
I have made sure the 'IKE and AuthIP Keying Modules', 'IPsec Policy agent', 'Remote access auto connection manager', 'remote access connection manager', 'Routing and remote access' and 'Secure socket tunneling protocol service' services are all set to automatic start up and are running.
The last 2 days every bit of help I've seen points to the AssumeUDPEncapsulation.... reg edit but that hasn't fixed my problem.
Has anyone had this issue before? I am trying to connect on a Toshiba Tecra but I don't think the laptop is the issue as the W10 Tecra's connect with no problem. I do not have the Intel Proset wifi management software installed.
Thanks in advance.
