You can use playit.gg or localtonet.com for making lan game reachable from internet to your friend and vice versa. For Diablo 2 Resurrected there’s a mod that allow to play on LAN (original blizzard version doesn’t have LAN) from here - it’s works out of the box. Here You can download original Starcraft 1.16.1 version installer. Works very good on LAN. Good luck!
