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.
