5. At this point the unit will attempt to raise the PPP connection. You can tell if it is successful by entering the
PPP command.
The connection stays up as long as the units are physically connected regardless of PPP activity; the unit does not
time-out the connection (unlike with a dial-up PPP connection). If the connection is broken then the unit goes into a
state of repetitively trying to connect again.
To bring down the connection there are two options:
1. Change the I/O 2 mode to something other than PPP CLIENT.
2. Enter the
PPP DOWN
command. (Note that in doing this, if the machines are still physically connected, the
unit will immediately try to bring up the connection again.)
Note that unlike dial-up PPP connections, the unit does not automatically make the PPP connection the default route.
Routing
The unit can route traffic received on this PPP connection to Ethernet. To configure this:
1. On the unit when it is used in HOST mode, enable PPP to Ethernet routing (
sk
net.ppprouting.enable
=on
)
.
2. On the unit when it is used in HOST mode, configure the Ethernet interface that you intend to route onto (Eth1
or Eth2, if the unit has more than one Ethernet interface). Do this with the
net.routing.if
setting.
Typically it is desirable to have traffic NAT'ed as it is routed; this happens by default and can be configured
with the
net.eth[].nat
setting, where the NAT-ing is enabled on the same interface that you configured
with the net.routing.if setting.
3. On the client machine, ensure that you configure it so that it knows to route traffic to your Ethernet address
through the host machine. You can do this by configuring a static route. If the unit is the client machine, this is
how you configure a static route:
1. Pick a static route slot x (e.g., 1) and enable it (
sk net.staticroute[x].enable
=on
).
2. Configure a destination network (e.g., 10.2.3.4/32, or 192.168.0.0/16) using the
net.staticroute[x].destnet
setting.
3. Configure the interface to be serial PPP (
sk net.staticroute[x].if
=SPPP
)
4. At this point you should be able to, for example, ping an Ethernet host in your static-route network
from the unit, via the PPP connection.
Example
To configure two units to connect to each other, where only one unit has an Ethernet connection, such that both units
can reach any host on Ethernet where the Eth1 interface network is configured as 10.2.3.0 on a 255.255.255.0
subnet:
First configure on the host unit (the one with the Ethernet connection):
serial[2].mode
=ppp host
serial[2].baud
=115200
net.firewall.ppp
=off
net.ppprouting.enable
=on
net.ppphost.localip
=192.168.105.1
net.ppphost.remoteip
=192.168.105.2
net.eth[1].nat
=on
net.routing.if
=ETH1
Then configure on the client unit (the one without the Ethernet connection):
serial[2].mode
=ppp client
net.pppdial.username
=admin
net.pppdial.password
=password
