DSL Routing
DSL routing is used to make the unit route, and do network address translation (NAT) on, NAT-capable traffic (TCP,
UDP, and ICMP) from the unit's Ethernet ports to the unit's DSL peer, and hence on to the Internet. For example, a
PC that uses one of the unit's Ethernet addresses as its default router can browse the web via the unit's DSL
connection. The DSL interface is firewalled such that only traffic related to already-existing-outgoing connections is
allowed in.
Configuration
The following Setting Keys need to be configured:
net.dsl.startmode
Set this to AUTO to tell the unit to automatically raise the DSL interface upon boot. Set this to MANUAL to require user
intervention to raise the DSL interface, or to let a VPN (if it is configured to use DSL) raise the DSL interface when the
VPN needs to use DSL. Values are MANUAL or AUTO. Default setting is MANUAL.
net.default.router
This setting allows you to select the default router (gateway) for the unit. Each network interface has a router setting
which you can configure; this is the machine on that interface to which frames will be sent if they do not route to the
local network of that interface. However the unit uses only one of those configured routers at this time. As you
configure router settings the unit will choose a default router for you. This is available for you to see (and override) via
this
net.default.router
setting. The values you may choose for this setting (i.e., router addresses) must be in the
set of routers which you have specified, or the special value, "DSL", which means that the DSL interface peer is the
default router. For DSL Routing, set
net.default.router
=DSL
.
The unit uses a routing table to determine how to send any outbound IP frame. Each entry in the routing table tells the
unit how to send a frame whose destination address matches a rule in the routing table. Routing table entries are
examined from most-restrictive to least-restrictive, so the default routing table entry is the last entry in the table since it
is the least restrictive. It is the catch-all route: it tells the unit how to send a frame when it doesn't know how else to
send it. The only routes on the unit at this time are network interface routes and the default route. Network interface
routes tell the unit how to send a frame bound for a machine on one of the unit's local networks (subnets). These
routes are automatically configured when you configure the address of a network interface. If an outbound frame is
destined for a machine off all local networks then it is sent according to what the default route specifies. The default
route specifies the default router to use for these frames.
If you have configured only one router for all of your network interfaces then you don't have to worry about this setting:
the unit configures it for you and there is nothing you can override it with. The default router is engaged as soon as it
is configured.
net.dsl.routing.enable
Set this to ON to make the unit forward frames received on either Ethernet interface (and not addressed to the unit)
out the DSL interface. Frames are NAT-ed as they leave the DSL interface. Frames arriving on the DSL interface not
associated with existing connections are blocked (the unit is firewalled). Note that the unit's default router must be set
to DSL (
net.default.router
=DSL
) for DSL routing to work. Set this to OFF to make the unit not do this. Values
are: ON or OFF. Default is OFF.
net.dsl.override
Set this to a non-zero value to enable ADSL web configuration access on the TCP port specified by the value. Set this
to 0 to disable web configuration access. Values are: 0 to 65535.
Default is 0.
