4. Data with Powerful DES Encryption If you are transmitting sensitive information such as cost estimates product plans and investment opportunities across the Internet you want to secure this data so that it is indecipherable to all but the intended recipients AT VPNet provides powerful DES or 3DES encryption Your data is scrambled before it is transmitted across the Internet making the data meaningless if intercepted Only the data portion of the IP packet is encrypted the address information required for routing the packet to its destination is unchanged AT VPNet uses a separate daughter card that fits inside the AR745 to offload the processor intensive task of data encryption so routing performance is not affected Note The export of strong DES based cryptography such as Al VPNet is subject to export controls in most countries Contact your distributor or reseller for details THE AR745 FEATURE SET The following are just some of the features provided by the AR745 e Wide area networking via Frame Relay Point to Point Protocol and X 25 e Basic Rate and Primary Rate access to Integrated Services Digital Network ISDN services with dial on demand bandwidth on demand and channel aggregation facilities e Multiprotocol routing including TCP IP Novell IPX DECnet AppleTalk and GRE Generic Routing Encapsulation protocols Supported routing protocols include RIP and RIP v2 EGP OSPF and Novell RIP and SAP e Te

7. When you connect to the Internet you have unrestricted access to the World Wide Web Likewise it has access to you To ensure that only authorised users can access your local network the AR745 has an extensive range of security measures including e A fully featured stateful inspection firewall which dynamically filters traffic flows based on manager defined rules All firewall events are logged to the router s Logging Facility and significant events generate notifications via SNMP traps email or triggers The firewall automatically detects and combats a range of denial of service attacks including SYN and FIN flooding Ping of death Smurf attacks and port scans Psec compliant security services e Calling Line Identification CLI which uses the ISDN address of the incoming call to verify that the caller is calling from an authentic location AR745 ROUTER QUICK START GUIDE 5 ISDN callback which verifies the caller using CLI disconnects the incoming call then calls the destination back to establish the link This allows a remote site to reverse the call charges to a central office for central billing of ISDN calls e PAP and CHAP to authenticate remote access using passwords and user names e TACACS and RADIUS for authenticating users The AR745 can query TACACS or RADIUS servers running on a network host to authenticate users A centralised database simplifies management of a large user population Protect Your
