My scenario is that I have two 4g internet connected to one device MX64 to wan1 and wan4, and configured as site to site HUB vpn, with Automatic NAT traversal.
And another MX64 device with another 4g internet connected to wan1. And configured as site to site spoke VPN to the first HUB as specified above.
I got the VPN established but I got message as NAT Type : Unfriendly.
And I am not able to ping connected to the LAN port of MX64 configured as HUB VPN.
Since I have all the WAN as AUTO DHCP. How should I configure :-
Manually create a port mapping on the upstream firewall that will forward all traffic received on a specific public IP and port to the internal address of the appliance on the selected port. In Dashboard on the Security & SD-WAN >Configure > Site-to-site VPN page use the Manual: Port forwarding option for NAT traversal, and provide the public IP address and port that was configured.
