Enhanced Link-Layer Compression Support

NETServer 8/16 Plus supports these link-layer compression

methods:

• STAC LZS - a compression mode that uses the LZS-based

algorithm ( the most common PPP algorithm)

• Microsoft PPC - a compression mode that differs slightly

from STAC, utilized by Windows 95 and NT

• Ascend - a compression mode based on STAC LZS with

differences in the way initial sessions and dictionary resets

are negotiated

Enhanced RADIUS Support

NETServer 8/16 Plus has the following RADIUS-related

features:

• RADIUS Challenge support - second level authentication

• Settable RADIUS retransmission parameters - the number

of retransmissions and time-out can be specified on the

primary RADIUS server

• Mirroring - accounting information is sent to primary and

secondary servers

Improved Security

NETServer 8/16 Plus supports a wide array of packet filters that

can accept or reject packets based on rules that you specify. You

can configure the NETServer to filter packets entering and

exiting NETServer ports using input and output filters. In

addition, you can apply these filters to a specific user. You can

also use call filters to allow or prohibit call initiation.

Filter types include:

Data filters - Perform filtering based on protocol-specific

information for IP, IPX and AppleTalk packets

Advertisement filters - Performs filtering based on information

contained in advertisement packets such as IP-RIP, IPX-RIP,

IPX-SAP, AppleTalk RTMP, and AppleTalk ZIP protocols
