It depends on your network configuration.  You should make
sure that when your network is *not* active (e.g., no ppp or 
Ethernet card not plugged into the network), you don't have
any routing or so configured.  In particular, check 

  netstat -rn

There shouldn't be a default route, i.e., no `Destination'
with 0.0.0.0 if there is no active network.

In my case, I encountered the problem, because I have a
combined Ethernet/modem card.  And when I plugged it in, to
use the modem, `cardmgr' also triggered the setup for
`eth0', which set up a default route (although, the card was
not connected to a network).  I could solve this by defining
different schemes (as supported by the PCMCIA package) for
my use of the Ethernet card.
