Site to site VPN with nat

Hello,

I am testing XG 17.5 to create a site to site VPN with nat. I did this configuration https://www.youtube.com/watch?v=mA_TaVDH5C4

In IPSEC I activated NAT and I select the Public IP that I need to nat my virtual IP to it.

The tunnel did not come up

I changed Local network to the Public IP, the tunnel came up but I can not access the remote network.

what should I do to NAT my virtual network through the tunnel?

Here is the configuration:

Local gateway port4 41.66.66.2

Local subnet 10.6.6.45 and must be NAT to public IP 41.66.66.29

Remote gateway 41.222.131.67

Remote subnet 10.71.127.72

Thank you in advance

George
