This has been a very challenging task but I was able to get it working after a lot of trials.

Task

You need to connect a AWS VPC running in Europe with a AWS VPC running in US.

Since i wanted to learn more about AWS I decided that i will be using the amazon VPN and connect it to a Vyatta/Vyos router running on the other end.

I will try to keep this simple.Once you have everything up and running go back and expand/secure everything.

This is not a in depth guide and i assumed you know how to setup a VPC, setup static routes ,assign IP’s etc…

VPC 1 ) Name US-VPC

IP Range : 10.100.0.0/18

Network ACL => default allow all both directions

1 public subnet 10.100.0.0/24

1 private subnet 10.100.1.0/20

1 public Route 0.0.0.0/0 => IGW

1 private route no 0.0.0/0 => nat instance

VPC 2) EU-Name EU-VPC

IP Range : 10.100.64.0/18

Network ACL => default allow all both directions

1 public subnet 10.100.64.0/24

1 private subnet 10.100.65.0/24

1 public Route 0.0.0.0/0 => IGW

1 private route no 0.0.0/0 => nat instance
