[NEBULA] NSG50 VPN L2PT Ipsec on WAN2 don't Function

Good Mornign have a problem on NSG50 and VPN L2PT Ipsec directly on WAN 2;

I have problems with the NSG50 and the WAN 2: 
I create a VPN account with credentials and related cloud authentication parameters and everything works on WAN1; 
If I move it all, on WAN 2 it doesn't work; Since I need to work on WAN1 or WAN2 I would like to know why. 
Thank you. Happy August.

Thanks Andrea Sdringola
