I have installed OpenVPN on two WR1043ND WiFi routers. All of them in my home - on desk 🙂
The server side is my "usuall" home router using UPC cable connection, visible from internet, using freeNDS.
The client side (now) connected to internet using HUAWEI E3372 LTE stick and a Raspberry PI as gateway. The router connected to RPI through WAN connector, and RPI serving as a gateway and DHCP server (similar to service provider).
The configuration of server and client side is here:

From the client site I can ping hosts on server site, even using ssh and scp.
From server site I can not see client.
I was trying with firewall on/off, but it does not help. - for client site it was even worth.
I ran out of ideas what cause the problem.
Any help will be highly appreciated!
