--------------------------------------
Summary: Allowing non rfc1918 networks on the other end of VPC
Site 2 Site VPN
Key: CLOUDSTACK-6747
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6747
Project: CloudStack
Issue Type: Improvement
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server, Network Controller, Virtual Router
Affects Versions: 4.2.0, 4.3.0
Reporter: Erik Weber
Priority: Minor
When you configure a Site 2 Site VPN Customer gateway the other end from
CloudStack point of view is not allowed to be outside rfc1918 address scope.
There are use cases where the client / remote networks use official/public
addresses and you want to encrypt / secure the traffic with VPN.

Expected behavior is that guest cidr should be allowed as long as it's a valid
cidr, including if it's outside of RFC1918
