Add a static route on the ISP's gateway 10.0.0.1, which specifies the host 10.0.0.217 as the gateway to network 192.168.0.0/24. Then all hosts on the ISP's network, including the server, will be able to communicate with the hosts on the LAN

if you are not the isp you would have to call them to add that it needs to be on their router if you are the isp all you nee3d is

add dst-address=192.168.0.0/24 gateway=10.0.0.217 scope=255 target-scope=10 comment="" disabled=no
