Specifying default routes on a per-user basis
You can specify a default route on a per-user basis by setting the parameter in
Ethernet > Connection > profile > IP Options > Client Gateway. When the IP
address of the user’s default route is set, the Pipeline routes IP packets in this
way:
1
The Pipeline consults its routing table to find a next-hop address.
2
If the next hop is the default route for the system (destination 0.0.0.0), the
Pipeline uses the per-user default address as a next hop instead of the
system-wide default route.
The unit also uses the per-user default if the normal routing logic fails to find
a route and there is no system-wide default route.
The Client Gateway IP address applies to routing all packets received on an
interface using that profile, regardless of the specific IP source address; therefore,
you can set this parameter when the profile belongs to another access router and
all hosts behind that router use the default gateway. While all packets arriving on
the interface using the given profile are affected, the Pipeline handles packets
from other users or from the Ethernet normally. In addition, this feature does not
alter the global routing table.
To configure a per-user route in the Pipeline configuration interface, you must set
the Client Gateway parameter in the IP Options menu of the Connection profile.
For example:
Ip options...
LAN Adrs=nnn.nnn.nnn.nnn/nn
WAN Alias=0.0.0.0
IF Adrs=0.0.0.0/0
Preference=60
Metric=1
DownPreference=120
DownMetric=7
Private=No
RIP=Off
Client Pri DNS=0.0.0.0
Client Sec DNS=0.0.0.0
Client Assign DNS=Yes
>Client Gateway=10.0.0.3
