Hi, I'd like to propose "site-to-site VPN between VRs" as a new feature for CloudStack 4.3.
Basically the VPC's site-to-site VPN currently only support to access remote peer which is a hardware VPN gateway. This feature would extend the support to other CloudStack VRs, which enabled CloudStack networks to communicate with each other through VPN. Original requirement at: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Site-to-Site+VPN+2.0 https://issues.apache.org/jira/browse/CLOUDSTACK-730 FS available at: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Site-to-site+VPN+VR-to-VR+functional+spec --Sheng
