Your default route is wrong. You want the default route to be the
"other" end of the PPP link. To accomplish this, edit your
/etc/ppp/ppp.linkup file and add the following:
#
# In all cases (since we've only got one) add his address as default
# gateway. This has the added benefit of making *any* packet routed
# off our network redial the link. Of course, this makes casual
# name lookups expensive.
#
MYADDR:
delete 0 0
add 0 0 HISADDR
You'll also want to add the "default" for the other end of the PPP link,
the address you specify in /etc/ppp.conf, as the defaultrouter in
/etc/sysconfig. This will provide a default route via the PPP link
*until* it actually comes up, causing the link to be demand dialed the
first time an off-site packet gets pushed through the link. I.e., if
your /etc/ppp.conf contains:
myIsp:
[...]
set ifaddr 200.100.50.43/24 200.120.47.8/24
you will want to make the *first* address your default route. The
'delete 0 0' command in ppp.linkup will delete the existing default
route before attempting to insert the new one each time the link is
brought up.
