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.
