title: AWS - Strongswan :: How to make clients from subnets communicate?
body: <p>I have successfully setup an IPsec VPN between 2 VPCs from 2 different regions via Strongswan and the 2 gateways are able to connect.
  The problem is that the other instances of a vpc/subnets are not able to ping the other vpc/subnet: 
  VPC A/gateway can talk to VPC B/gateway... 
  VPC A/Instance can talk to VPC A/Gateway
  Same applies for VPC B... But
  VPC A / Instance can NOT talk to VPC B/Gateway B or VPC B/ Instances ( Same applies for VPC B to VPC A).</p>
  
  <p>I have checked and tried to play with the routes of table 220 and also ICMP redirects, no way.</p>
  
  <p>Anyone can assist please?</p>
  
  <p>Regards.</p>
