Yes it is possible, if you mean
eth0 connected to a cable modem
ppp0 connected to a modem on a phone line
Having the two connections themselves isn't really any harder than the
separate work of setting each one up. What is hard is the routing table. In
the simple sorts of static-routing setups typical for Linux routers, one or
the other will be the default route and get all traffic not explicitly
routed to the other.
To have both interfaces, you need either to run a fancier routing protocol
or to "bridge" the interfaces. For the first, look at zebra. The second is
ISP specific and probvably not a real option for you.
A more common setup is a failover system, in which the router periodically
checks that the cable-modem link is up and, if it isn't, starts the ppp
interface and changes the default route to it. Then it keeps monitoring eth0
until it comes back, at which point it drops ppp0. It's a bit tricker than
I've made it sound, but people do get it working (there's been discussion of
this on the [EMAIL PROTECTED] mailing list).
BTW, I don't know this area in much more detail than what I've written here.
So general follow-up questions won't get helpful answers (at least not from me).
