VPN

The VPN addon provides a fixed-ip outgoing node. This can be used to work with services protected by ip address filtering. VPN_ADDON_* variables will be provided by Clever Cloud upon setup, the only configuration you have to provide is a list of CIDRs (eg. 1.2.3.0/24) for which you want the traffic to be routed through the exit node.
