No puedo conectar mi computadora desde LAN (http, smb)

Question

Instalé ubuntu 10.04, Apache, PHP, mysql, smb. Todo funciona bien localmente en mi IP. Cuando intento acceder a mi computadora desde LAN (otra computadora), aparece que no puedo conectarme. cuando hago ping a mi IP desde una computadora remota, el ping está bien. Puedo acceder a Internet y a todos los demás sistemas (http, smb). Pero el problema es que nadie puede acceder a mi computadora de forma remota en mi red LAN.

Mi IP es 192.168.85.105 y quiero acceso (Appaceh, SMB) desde 192.168.85.10.

¿Existe alguna configuración de firewall proxy?

Cuando reinicio el sistema, el mismo problema todavía existe. El sistema hace ping correctamente desde el host remoto. He ejecutado los comandos anteriores. Inicialmente ejecuto el comando "sudo iptables -F", está bien la primera vez. ahora no funciona, por favor ayúdenme...

¿Cambiaste la configuración de tu ip-table? Intenta restablecer iptables

sudo iptables -F

o

sudo iptables-restore

[es necesario cerrar sesión] Si no funciona, intente desactivar el filtro de red

sudo ufw --disable
