1. Introduction to Hotwire DSL Routers
Hotwire DSL Router Features
Hotwire DSL routers contain the following features.
IP routing with:
—NAT (Network Address Translation)
—NAPT (Network Address Port Translation), also called PAT (Port Address Translation)
—Simultaneous Basic NAT (for several fixed servers) and NAPT (on the rest of the PCs on the LAN)
—DHCP Server (Dynamic Host Configuration Protocol) and DHCP Relay Agent
—A full set of IP filters, two per DSL card (one for upstream and one for downstream traffic), with up to 33 rules per filter
—SNMP Set/Get capability
Three Configurable Modes of Operation. Supports the following modes of operation:
—IP routing only
—IP routing, and bridging of all other protocols (using VNET mode)
—Bridging all protocols (using VNET mode)
Protocol Filters. Provides the ability to:
—Filter MAC frames when bridging
—Configure two Ethertype filters via the Hotwire DSL card, one for upstream and one for downstream traffic, with up to 16 filter rules per filter
—Compare the Ethertype in frames to a particular value, or configured set of values, to perform filtering
—Support ICMP (Internet Control Management Protocol) filters for firewalls via the Hotwire DSL card, based on the ICMP message type, to selectively discard some ICMP message types while forwarding others
High-speed Internet or intranet access.
Diagnostics. Provides the capability to diagnose device and network problems and perform tests.
Device and Test Monitoring. Provides the capability of tracking and evaluating the unit’s operation.
Remote Firmware Download. Provides easy setup and activation of firmware upgrades from a remote location.
Security. Provides multiple levels of security, which prevents unauthorized access to the DSL router.
