VPN connection no internet to clients

i have a fritzbox and from lan it goes into wan port of gli router AXT1800 Flint.Then i enabled and tried open vpn and wireguard server.Both can connect.I am using a travel 1800AXT router.
The travel router connects with my personal hotspot from mobile nad then i connect to wireguard vpn or to vpn.It works but then the clients dont have internet or i cannot ping the fritzbox.The Flint router has an ip in the same subnet of fritzbox.I can connect to it when i am with wireguard vpn and not with open vpn.What should i do?


Please check if your fritzbox ip range is the same with VPN tunnel. Refer to
