The only place you are getting an IPV4 address is ppp0.  And to get that 
you are running pppoeconf.  Are you equipt with some sort of a phone 
modem card in your machine?  I have a bag of those things but its been 
15 years since I last actually used one.  In the above sampling, 2 
things are dead wrong.

1. Mask is restricted to the exact address when the setting is 
255.255.255.255.  Much more normal would be to zero the last triplet.

2.  That however would still block the P-t-P address as its in a 
different block of 255 addresses.  You would have to zero the last 2 
triplets before you could even ping the P-t-P address shown.

My memory is fuzzy at best as its also 80 yo, so if you are truly dealing 
with a modem card and a dialup phone line, someone who has done this 
recently needs to chime in and advise.  I am not equipt with recent 
enough experience to be of any help.


Everything that I have written assumes the first rj45 jack is connected 
to a router, and that the router is connected to a ca ble or DSL modem.
