How to give access to a computer from the zone of the VPN server to the WAN port of the VPN client?

Question

openvpn

So there is:

• Home network (network 192.168.1.0 ) . An OpenVPN server will be set up on the OpenWrt router. Internet with white IP.
  
• Remote point (network 192.168.0.0 ) . There is also a router with OpenWrt, where the OpenVPN client will be installed. Internet via 4G modem, which pretends to be a network interface with ip 192.168.1.1 and which has a web face.
  

With mutual access to devices in the client and server networks, everything seems to be clear. But I can’t understand another thing - how can I get access from the server network to a device connected to the client’s WAN port (i.e. I want to go to the modem’s web face from home)?
Being in the client's network, typing 192.168.1.1, I calmly go to the modem's web face.
