Hi all,

This is easy. First let ppp0 as your default gateway and 
use iproute to create a table call any name you want and 
then you put ppp1 default route inside that table. After 
that you have to create a rule to put the host you would 
like insede it and dont forget to put a rule in the 
iptables saying that everything going out via ppp1 SNAT -
-to IP_PPP1_EXTERNAL. ;)

routing in the advanced routing howto to the letter but i

ing up ppp0 as the deafult gateway for only one computer 
(10.0.0.11), as it says at http://lartc.org/howto/lartc.r
pdb.html#LARTC.RPDB.SIMPLE I've done everything it says t
here and im 99% sure I've put the right ip addreses in et
c.  When Ive gone through it that computer is no longer a
ble to access the net (the rest of the network is unaffec
ted).

orks fine but obviously thers no point in that.
