[techtalk] Building ADSL - LAN

[Just This Girl]

First off, I would like to thank everyone who wrote back with their
advice and reading suggestions.

However, I am still having the following problem.

I have gotten to the Internet through my ADSL modem from my Windows98
partition.
What follows is the route PRINT from the command prompt while running
Windows98:

Network Address   Netmask           Gateway Address   Interface
0.0.0.0           0.0.0.0           xxx.yyy.zzz.246   xxx.yyy.zzz.242
127.0.0.0         255.0.0.0         127.0.0.1         127.0.0.1
xxx.yyy.zzz.240   255.255.255.248   xxx.yyy.zzz.242   xxx.yyy.zzz.242
xxx.yyy.zzz.242   255.255.255.255   127.0.0.1         127.0.0.1
xxx.yyy.zzz.255   255.255.255.255   xxx.yyy.zzz.242   xxx.yyy.zzz.242
224.0.0.0         224.0.0.0         xxx.yyy.zzz.242   xxx.yyy.zzz.242
255.255.255.255   255.255.255.255   xxx.yyy.zzz.242   xxx.yyy.zzz.242

TCP/IP on Windows98 is set up as follows:
Gateway: xxx.yyy.zzz.242
IP Addr: xxx.yyy.zzz.242
Netmask: 255.255.255.248

The ADSL modem is configured with:
Gateway: xxx.yyy.zzz.246
IP Addr: xxx.yyy.zzz.241
Netmask: 255.255.255.248

The ADSL modem is an Alcatel 1000. The NIC above is a 3COM EtherLink III
3c509B. I have done the set-up, disabled PNP, and all those goodies. The
addresses referenced with xxx.yyy.zzz.### are public IP addresses, not
private.

What I am having problems with is duplicating the successful Windows98
routing under the Linux partition, the partition I -really- want to run
full-time.

However, when I ifconfig eth0 (the NIC under Linux) using this:

ifconfig eth0 xxx.yyy.zzz.242 

it automatically inserts this into the route table:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
xxx.yyy.zzz.240 0.0.0.0         255.255.255.248 U     0      0        0
eth0

Note the gateway. I want xxx.yyy.zzz.242 as the gateway, NOT 0.0.0.0,
but it will not let me delete this route to readd it. This is the error
I get:

bash# route del -net xxx.yyy.zzz.240
SIOCDELRT: Invalid argument

What I -think- I should be typing to get the routing displayed in
Windows98 is:

route add default gw xxx.yyy.zzz.246
route add -net xxx.yyy.zzz.240 gw xxx.yyy.zzz.242 netmask
255.255.255.248
route add xxx.yyy.zzz.242 gw localhost
route add xxx.yyy.zzz.255 gw xxx.yyy.zzz.242
route add -net 224.0.0.0 gw xxx.yyy.zzz.242 netmask 224.0.0.0
route add 255.255.255.255 gw xxx.yyy.zzz.242

However, Linux complains and moans about the last two entries.

Do I have an old version of route? My version is: 

bash# route -V
net-tools 1.52
route 1.96 (1999-01-01)

I would appreciate any input on what I am doing wrong here.
