Hi, team!


This post is about the issue of the incoming VPN not working. Please see more information as it is displayed below.


ISSSUE DESCRIPTION


We have installed a new AR169W router (replacing a Netgear R7000P) client to connect to an SBS server that is connected to the router. There is no fancy configuration on the router, as it is very basic.


Huawei AR169W


Have done a nat (TCP and UDP) for 1723 towards the SBS server (192.168.2.2) in the router.


When the client tries to connect, I am getting the following error on the server 'The connection between the VPN Server and VPN client has been established, but the VPN connection cannot be completed.'


ROOT CAUSE


The most common cause for this is that a firewall or router between the VPN client is not configured to allow GRE packets (protocol 47).


On the client, I am getting that the IPsec negotiation might not be configured correctly. Please note the router is a passthrough only and there is no VPN client enabled.


With Netgear, according to the client, there would be no problem at all.


Any tips or help will be highly appreciated regarding this issue of the incoming VPN not working.


Regards,


RK

Hi Team
Fixed the issue by enabling the PPTP on the router - please use the command "nat alg pptp enable" or from the Web GUI - go to IP Services .. NAT page and CHECK ON THE PPTP box
