Hi everybody i'm new here please help me in my problem.... i'm windows technicant and i'm trying to become a linux user.....step by step. ok... i installed an ispconfig in my debian webserver and all is going fine but i can access to ispconfig panel only by local network for example if type in the browser https://192.168.0.22:81 i see the isp config page if i type from a pc in a same network https://192.168.0.22:81 ok but if assign to debian an a public ip adress like 88.33.145.66 (for example) and from a pc connected to internet (in another place) https://88.33.145.66:81 nothing. i think is a restriction but where?

Are you behind a router ?
Firewall active on router ?

Maybe you should try to activate the DMZ on your 192.168.0.22 machine or port foward the port 81 on your server ?
