I have a RedHat Linux 5.1 Box on my network. I have my network interface
and default gateway point to the router on my network which route to a
different office. I put a modem in my Linux box and try to connect to my
ISP using PPP. I can get the modem to dial and connect. But I have a hard
time getting the local ip-address assigned by the ISP, and default route
change to the PPP0 interface. On the /var/log/messages, I see that my ppp
connection is established and connected, but the remote ip address is the
isp address, but the local ip address is my network interface. If I took
out the network interface ip address and change the gateway to use the PPP0
interface, then PPP works fine. I need to be able to connect to my own
network and dial out at the same time. Can any one help?

By definition there can't be two active default routes. Pppd won't
automatically replace an existing default route. To get an active
default route to ppp0 while connected to the ISP you can put

/sbin/route add default ppp0

in /etc/ppp/ip-up. Once the ppp connection is down the default route
to your network will again become the active default route.

To get to any place on your network, regardless of the default route,
you only need a specific network route of the form

/sbin/route add -net ${NETWORK} netmask ${NETMASK}

Do you use the defaultroute setting with pppd? (propably in your
provider.options file)

It will add the defaultroute to the routing table. Default route means
0.0.0.0 - networks will then be accessed with your assigned IP-address
