Description of Problem:
at the connection, an IP route is correctly added to the ISP gateway through
ppp0 device, but a default route (any IP not belonging to my local area network
must be routed to ppp0) should be added too, like rp3 does using a standard
modem. I'm using an ASDL modem on eth0.

Version-Release number of selected component (if applicable):
rp-pppoe 3.3-7

How Reproducible:
always

Steps to Reproduce:
1. Create ADSL connection
2. Activate it
3. 

Actual Results:
Host isolated from internet until I add manually the correct route; besides,
there is no way to add a default route through a device, not a gateway, from
the cration mask of the pppoe connection...

Expected Results:
functional connection

Additional Information:

before the connection my route table is:
192.168.8.0     *               255.255.255.0   U  0 0 0 eth0
127.0.0.0       *               255.0.0.0       U  0 0 0 lo
default         erihome         0.0.0.0         UG 0 0 0 eth0

after the connection it should be:
151.5.152.134   *               255.255.255.255 UH 0 0 0 ppp0
192.168.8.0     *               255.255.255.0   U  0 0 0 eth0
127.0.0.0       *               255.0.0.0       U  0 0 0 lo
default         151.5.152.134   0.0.0.0         UG 0 0 0 ppp0
default         erihome         0.0.0.0         UG 0 0 0 eth0
...or something like this; instead is like that:
151.5.152.134   *               255.255.255.255 UH 0 0 0 ppp0
192.168.8.0     *               255.255.255.0   U  0 0 0 eth0
127.0.0.0       *               255.0.0.0       U  0 0 0 lo
default         erihome         0.0.0.0         UG 0 0 0 eth0
without the default route through ppp0.
