Small Problem about Default Gateway

I have Ubuntu linux Os with two eth cards. I can easily delete def gatewayg. But I can't add new one.. SmilieSmilie

When I run route-n:

Code:
alperen@alperen-System-Product-Name:~$ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.2.0     0.0.0.0         255.255.255.0   U     1      0        0 eth1
10.20.0.0       0.0.0.0         255.255.0.0     U     1      0        0 eth0
169.254.0.0     0.0.0.0         255.255.0.0     U     1000   0        0 eth1
0.0.0.0         10.20.0.1       0.0.0.0         UG    0      0        0 eth0



I delete the default gw using


Code:
alperen@alperen-System-Product-Name:~$ sudo route del default gw 10.20.0.1

alperen@alperen-System-Product-Name:~$ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.2.0     0.0.0.0         255.255.255.0   U     1      0        0 eth1
10.20.0.0       0.0.0.0         255.255.0.0     U     1      0        0 eth0
169.254.0.0     0.0.0.0         255.255.0.0     U     1000   0        0 eth1


Now I try to add static gateway using:
Code:
alperen@alperen-System-Product-Name:~$ sudo route add default gw 169.10.10.100 
SIOCADDRT: No such process
alperen@alperen-System-Product-Name:~$ sudo route add default gw 169.10.10.100 
SIOCADDRT: No such process


I also tried ip route commands..

I don't see how either interface can see 169.10.10.100. Make sure the gateway is visible in order for it to be the default gateway. Then I would add the interface dev as the last parm to your route add command (e.g. eth0 or eth1).
