Hello, I'm setting up a site to site vpn between two networks under the same organization. The site A has the 2 MX WANs directly connected to the 2 router meanwhile the site B has the WAN port connected to a load balancer and the load balancer is connected to the 4 routers we have. I have this error on the site B "This WAN appliance is behind a VPN-unfriendly NAT, which can be caused by upstream load balancers or strict firewall rules." The network configuration in the site B is : I open the ports I need for my services on the 4 routers, the load balancer has a port forwarding for ALL the ports (1-65535)to the MX. I reckon there is something that the auto vpn site to site doesn't like. Someone could help me please? Thanks a lot!
