Wire-guard Point to Point server is on cloud with Linux 18.4 OS
I connected other computer as client based on Windows and Linux they work just fine, Good connection and speed.
But when I am trying to setup Openwrt router Device information:
TP-Link Archer C7 v5
It won't work at all . Once connection was established as per implementation provide on openwrt.org, Packets were going back and fourth but no IP change.
Firewall setting I made as per WAN port.
In this setup I have my main router and a TPlink router as DHCP client on WAN port.
Now My Questions are ?
Do I need to setup this router as Client or Server ?
I assume you have an OpenWrt router with a LAN, all the users in the house are on the LAN side of this router, and the WAN side of this router is connected to your ISP router but nothing else is connected directly to the LAN side of the ISP router. In that case just consider the ISP router as part of the Internet, and the VPN will tunnel through it. No special configuration is needed on it.
Your other clients were road warriors, meaning they were a single machine with a single IP on the VPN. Now you're setting up a whole network on the client side. So on the server, you need to add your LAN IP subnet as allowed_ips for this client. On the router, allowed_ips is 0.0.0.0/0 since you want any site on the Internet to come back through the VPN.
Another approach (used with commercial VPN services where you can't configure the server) is to NAT the local LAN into the VPN tunnel, treating it like an ISP. That is achieved simply by placing the VPN tunnel in the wan firewall zone instead of lan. In that case your road warriors won't be able to reach the local LAN unless you forward ports in the firewall.
Although not a hard rule, typically the "server" listens for a connection that is initiated by the "client" -- so if this is the server, it is strange how it is formatted. Aside from this, the network definitions are going to be problematic, for sure. I think your 'server' (if that's what we are looking at) needs to be completely overhauled.
Can you please post your OpenWrt network/firewall config files?

But still my IP hasn't change
