2.2. Security features
The OmniConnect/ISDN access device provides the following security features:
•
PPP authentication support, including Password Authentication Protocol
(PAP) and Challenge Handshake Authentication Protocol (CHAP)
•
Password security for local and remote telnet and configuration access
•
TCP, UDP and IP filtering based on source and destination IP addresses,
source and destination ports TCP and UDP ports, and IP packet types.
•
Network Address Translation and Port Address Translation. All local,
private IP addresses are translated to a single, globally unique IP address,
with a unique port number, thus hiding the local station’s addresses and port
numbers from external users. Unless specifically authorized, no externally
generated connection can create a connection with an internal client.
