The KEN! Proxy Server
KEN! – 5 KEN! for the Network Specialist 93
The KEN! Proxy Server
The KEN! proxy server conducts communication with the
World Wide Web on behalf of all workstations in the network
(see the illustration). This grants multiple workstations Inter-
net access at the same time via one ISDN connection. Surf-
ing in the Internet is easier and more secure than with a rout-
er!
Internet communication with KEN!
The KEN! User’s browser (e.g., Internet Explorer or Netscape
Navigator) addresses the KEN! proxy through the user’s own
network. The KEN! proxy uses the ISDN access to the Internet
provider to request the Internet address (URL) on the user's
behalf and to forward it to the KEN! User. The KEN! proxy can
serve multiple users at the same time.
The proxy settings of the browser on the workstations are:
• Proxy server address: the LAN IP address of the KEN!
Service PC, in the example network 192.168.115.1.
• Port: 3128 for FTP, HTTP 1.1 and secure
• Port: 1080 for SOCKS 4a/5
• KEN! supports autonomous FTP applications like WS-
FTP and CuteFTP through the FTP gateway at port 2121 or
port 21.
