direct connections. A single Internet access can be used to establish
multiple simultaneous logical connections to a variety of remote
stations.
The resulting savings and high flexibility makes the Internet (or any
other IP network) an outstanding backbone for a corporate network.
1.3 Firewall
The integrated stateful-inspection firewall is an effective barrier to
unwanted data traffic as it only permits the entry of data as a response
to outgoing data traffic. The IP masquerading function in the router
conceals LAN workstations accessing the Internet behind a single
public IP address. The true identities (IP addresses) of the individual
workstations remain masked. Router firewall filters allow the
blocking of individual IP addresses, protocols and ports. MAC
address filters also offer effective control over the access of LAN
workstations to the IP routing functions in the device.
Further important features in the firewall are:
• Intrusion detection
Attempts to break in to the local network or central firewall are
recognized, repelled and recorded by the Intrusion Detection
System (IDS) in the SwyxConnect. There is a choice of alarms
including in-device logging, e-mail messaging, SNMP traps or
SYSLOG alarms.
• Denial-of-Service protection
In addition to conventional break-ins, attacks from the Internet
may aim to block the availability of individual services. For this
reason, the SwyxConnect router is equipped with appropriate
security mechanisms to recognize popular hacker attacks and
guarantee router functionality.
