Hi all,

I draw my configuration of ethernetcards:

PC (eth0 10.0.0.1)-->3com switch-->speedtouch(10.0.0.138)-->theNet
PC (eth1 192.168.1.10)-->FSG (192.168.1.1)-->speedtouch(10.0.0.138)

Now Fedora default creates the following route:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use 
Iface
10.0.0.0        *               255.255.255.0   U     0      0        0 eth0
192.168.1.0     *               255.255.255.0   U     0      0        0 eth1
169.254.0.0     *               255.255.0.0     U     0      0        0 eth1
default         FSG.lan         0.0.0.0         UG    0      0        0 eth1

If it does, I have no internet connection. Then I have to enter the 
following incantation to get internet connection:

route add default gw 10.0.0.138
route del default gw 192.168.1.1 (this one is optional??)

After which the default route goes over the speedtouch in stead of the 
FSG and I *do* have internet connection.
However, when I restart Fedora, I have to enter these commands again.

The question is now: how do I get Fedora to remember that I want the 
default route over 10.0.0.138 (or eth0) and not over 192.168.1.1 (or eth1)?

P.S. i read in an old book from 1995 by Matt Welsh and Lar Kaufman 
(Running Linux) that the metric can be used to have the system choose 
predictably (lower metric is more preferred), but I can seem to find 
this parameter in the fedora GUI tools....

P.S. 2. The FSG is the Freecom Storage Gateway: a network device with 
storage. Regrettably it is not a switch....

Anyone an idea how to get Fedora to set the default route correctly 
(i.e. as I want it)?

Guus.
