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
