Update: This seems to be a specific usecase, and only applies to "VPN concentrator" mode MX's with both internal/mpls as public connectivity. When it is a "VPN concentrator" to "VPN conecentrator" the VPN registry log shows always just the public "peer_contact" IP, even when the tunnel is set up over private IP: VPN tunnel connectivity change vpn_type: site-to-site, peer_contact: 217.x.x.x:42111, connectivity: true When it is a spoke hub connection the VPN registry log shows the correct "peer_contact" as an private IP. VPN tunnel connectivity change vpn_type: site-to-site, peer_contact: 10.3.x.x:42111, connectivity: true Regards, Frank
