What do you want to route through 192.168.123.254? What is behind the router?

Why did you need to take down eth0? Deleting the default route before dialing
up should be enough to have both, the LAN reachable and the Internet through
ppp0.
But I just learned, that you can have more default routes and prioritize them
using the metric. If your pppd is complaining, "not replacing existing
default route", set the metric of route_eth0 to 10 and add the two lines to
conf.d/net:
config_ppp0=("null")
routes_ppp0=("default dev ppp0 metric 9")
And ln -s /etc/init.d/net.lo /etc/init.d/net.ppp0
This should add the favoured default route over ppp0.
