You can have a site-2-site vpn with dynamic IP addresses.
In my situation I used this blog.: https://blog.pessoft.com/2016/05/29/mik ... s-and-nat/

In your case you have to run the script (for updating DDNS) only at the 20 sites.

In site B I using dcom 4g, I get is Local IP ( same 192.168.0.1/24) from ISP to access Internet so it cannot NAT.

When your 4G router really uses 192.168.0.1/24 you have an interesting problem at hand.
Your easiest solution would be either to change the main site LAN address (e.g. to 10.0.0.1/24 or 192.168.100.1/24)
or to change the local network address of the 4G routers (when that is possible).

When both are impossible, well you will have to craft some really ingenious solution that probably is not easy for a beginner.... so first consider the above.

I can edit your Lan of Site B. So you can support for me?
