Tenho um PC com dual boot Pop OS/Windows; instalei o Jellyfin (servidor de mídia) e o Sunshine (Jogar remotamente) no Pop OS e não consigo acessar nenhum deles através de outros dispositivos em LAN. Meu firewall está inativo e consigo pingar PC a partir do celular e meu celular a partir do PC. Além disso, instalei o Jellyfin e o Sunshine no Windows e consigo acessar perfeitamente. Também fiz o teste com

python3 -m http.server 8080 --bind 0.0.0.0

e não consigo acessar.

$ sudo iptables -L -n -v
