| Sujet : Qu'est ce qu'un serveur NAT | |
| Le_poilu | euuh on a jamais dit k'un NAT etait un firewall ...
ça peut etre un prmemeir pas vers la securite d'un reseau grave au filtrage des paquets IP bon plutot ke de se prendre la tete une eptite recherche sur google m'a donne ça: http://www.ietf.org/html.charters/nat-charter.html et j'ai trouve ça: [citation]NAT automatically provides firewall-style protection without any special set-up. That is because it only allows connections that are originated on the inside network. This means, for example, that an internal client can connect to an outside FTP server, but an outside client will not be able to connect to an internal FTP server because it would have to originate the connection, and NAT will not allow that. It is still possible to make some internal servers available to the outside world via inbound mapping, which maps certain well know TCP ports (e.g.. 21 for FTP) to specific internal addresses, thus making services such as FTP or Web available in a controlled way[/citation] ici : http://www.vicomsoft.com/index.htm [...] k=internal desole mais j rie ntrouve de tel en français ..mais c pas tellement complike à lire |
