^ Forum  Netzwerk  #816588 Firewall - Konfiguration joa__chim 31.03.2003, 15:49:26 Möchte meine Firewall so konfigurieren, daß alle Ports gesperrt sind außer 80, 20, usw. Hat jemand eine Liste bzw. Link wo die genutzten Ports der gängigen Dienste/Programme/Anwedungen zusammengefasst sind (z.B: HTTP - Port 80, FTP - Port xxx, ICQ - Ports xx, xxx, xxx)? LG Joachim ^ Forum  Netzwerk  #816630 Re: Firewall - Konfiguration Qbus 31.03.2003, 16:18:45 PORT NUMBERS (last updated 2002-12-03) The port numbers are divided into three ranges: the Well Known Ports, the Registered Ports, and the Dynamic and/or Private Ports. The Well Known Ports are those from 0 through 1023. The Registered Ports are those from 1024 through 49151 The Dynamic and/or Private Ports are those from 49152 through 65535 ### UNASSIGNED PORT NUMBERS SHOULD NOT BE USED.  THE IANA WILL ASSIGN THE NUMBER FOR THE PORT AFTER YOUR APPLICATION HAS BEEN APPROVED ### WELL KNOWN PORT NUMBERS The Well Known Ports are assigned by the IANA and on most systems can only be used by system (or root) processes or by programs executed by privileged users. Ports are used in the TCP [RFC793] to name the ends of logical connections which carry long term conversations.  For the purpose of providing services to unknown callers, a service contact port is defined.  This list specifies the port used by the server process as its contact port.  The contact port is sometimes called the "well-known port". To the extent possible, these same port assignments are used with the UDP [RFC768]. The range for assigned ports managed by the IANA is 0-1023.
