Hey guys, I guess I could use some help from you.

My home network is connected to a TP-Link Archer C3200 Router.
The Internet connection type of this router is set on "Static IP" and connected to an external DSL Router and everything works just fine.
A couple of weeks ago I bought a TL-MR6400 4G LTE Router because I want to try to use a mobile network instead of DSL line to access the internet.
The problem is that mobile networks are NAT, so my Public IP it's not accessible, Dynamic DNS services cannot be used and I coulnd access to my home networks, domotics and cameras but I read on internet that using a VPN tunnel to a virtual server I could use the public IP of that server to access my network.
So, I rented a VPS server, installed a IPSec VPN server ( https://github.com/hwdsl2/setup-ipsec-vpn), tested it with my android phone and it works correctly.
Now, my question is: would it be possible to use the "IPSec VPN" section of my router to connect my network to that VPS server?
Here is the emulator if you want to have a look at those settings under Advanced > VPN > IPSec VPN > Add :
