IPSEC and NAT

I need to set up a vpn between different locations, but can't figure it out.

Most of ours sites belong to a MPLS network, and get to internet through the same public IP address. I can use port redirection on this IP but only for UDP and TCP, not for HA and ESP. I hope ipsec can work with only udp port 500 and 4500 redirection, but I can't figure how to force it. Is it at least possible, it's not clear for me.

I have meraki routers in the MPLS and an NSX Edge on the other side.
