Configure Router for Windows VPN Server
« on: April 15, 2019, 12:41:00 PM »

Hi,

I had a router with DD-WRT firmware running ahead of our Windows VPN server.  I just swapped it out for a DIR-865 and now I can't get the tunnel working. My current settings:

Connection: Dynamic IP (DHCP)  (I have Cox cable)
Subnet Mask 255.255.255.0
Enable DNS Relay: (tried both on and off)
DHCP Server: on
I have Virtual Servers and Port Forwarding set up to forward 1723 and 47 to the Server's IP address 192.168.1.111
I disabled SPI
Set NAT endpoint filtering to Independent
Currently I have checked all ALG options.  I started with IPSec (VPN) unchecked.
I enabled WAN Ping Response for troubleshooting

I can ping the external IP address successfully, but when I try to connect it says:
Connecting to VPN (briefly)
Verifying your sign-in info...
Then hang for a while, and tries again.
Finally I get an error saying "Can't connect to <VPN>.  The remote connection was not made because the attempted VPN tunnels failed.  The VPN server might be unreachable.  If this connection is attempting to use an L2TP/IPsec tunnel, teh security parameters required for IPsec negotiation might not be configured properly.

Any hints on how to troubleshoot, or what setting I might have wrong?

Thanks!
