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
