Morten,

Can you open a web browser within your ec2 instance and go to ipchicken?
Does the ip it detects match the static ip you assigned to the ec2 instance?

Morten – this sure sounds like your provider is intending for you to
establish a “site-to-site” tunnel between network equipment, as opposed to
a “client-to-gateway” connection.  If it were the latter, than the provider
would be telling you how to make that connection and what client software
to use.****

Hi,****

** **

I'm pretty new to VPN so I am looking for much appreciated help.****

** **

We need to connect to an external system/API, which requires a
VPN-connection.****

 From the provider we have received information on the ip address on the
VPN peer and a preshared key. Further we had to give them our public ip in
order to restrict connections from just our ip.****

** **

I setup an AWS EC2 Instance (Windows) and installed Shrew Soft VPN. I am
then trying to connect to their ip with the preshared key using IPSec, but
the only thing showing up is:****

** **

     bringing up tunnel ...****

     negotiation timout occurred****

     tunnel disabled****

** **

One thing I notice in the VPN Trace tool is that "Destination" is our
servers private ip address and not the public ip address that we gave them.
****

On AWS EC2, it does not seem possible to register the network interface
with the public ip. Is there a way to override this destination ip?****

** **

How can I debug this further?****


Hi Morten,

So your EC2 has a private IP and is NATted to a public IP on the way out? Have you tried playing with the NAT settings in the Shrew client Site Configuration?
