Vpn Passthrough - ZyXEL Communications ZYAIR G-5100 User Manual

ZyAIR G-5100 User's Guide
SSL Passthrough
SSL (Secure Sockets Layer) uses a public key to encrypt data that's transmitted over an SSL
connection. Both Netscape Navigator and Internet Explorer support SSL, and many Web sites
use the protocol to obtain confidential user information, such as credit card numbers. By
convention, URLs that require an SSL connection start with "https" instead of "http". The
ZyAIR allows SSL connections to take place through the ZyAIR.

VPN Passthrough

VPN (Virtual Private Network) connections use data encryption to provide secure
communications over unsecure networks (like the Internet). The ZyAIR allows VPN
connections to go through it.
Brute-Force Password Guessing Protection
The ZyAIR has a special protection mechanism to discourage brute-force password guessing
attacks on the ZyAIR's management interfaces. You can specify a wait-time that must expire
before entering a fourth password after three incorrect passwords have been entered. Please
see Appendix L on page 246
Wireless LAN MAC Address Filtering
Your ZyAIR checks the MAC address of the wireless station against a list of allowed or
denied MAC addresses.
WEP Encryption
WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless
network to help keep network communications private.
IEEE 802.1x Network Security
The ZyAIR supports the IEEE 802.1x standard to enhance user authentication. This allows
you to use a RADIUS (RFC2138, 2139 - Remote Authentication Dial In User Service) server
to authenticate users.
Embedded RADIUS Server
The ZyAIR's embedded RADIUS server eliminates the need to purchase and maintain a
standalone external RADIUS server. Use the embedded RADIUS server to authenticate up to
32 users. You can also use an external RADIUS server to authenticate a potentially unlimited
number of users.
Backup RADIUS Server
You can configure the ZyAIR to use backup external RADIUS servers and accounting servers
in case the primary external RADIUS or accounting server does not respond.
