How to set the Default gateway
Solution 1
ifconfig
is not the correct command to do that.
You can use route
like in route add default gw 192.168.0.254
for example.
And if route
is not present, but ip
is, you can use it like this: ip route add default via 192.168.0.254 dev eth0
, assuming that 192.168.0.254 is the ip of your gateway
Solution 2
ifconfig
is deprecated on Linux and furthermore, it's the wrong tool for the job. To set the default gateway on Linux use the ip
command as follows:
ip route add default via <host> dev <dev>
# e.g.
ip route add default via 192.168.0.101 dev eth0
Solution 3
For remove gateway in Linux Command : route delete default gw 192.168.1.1 eth1
For add gateway in Linux Command : route add default gw 192.168.1.250 eth1
Solution 4
Using route
route add default gw {IP-ADDRESS} {INTERFACE-NAME}
example: route add default gw 192.168.1.2 eth0
OR use hostname such as dsl-router:
route add default gw dsl-router eth0
Or use the ip command (newer syntax) to route all traffic via 192.168.1.254 gateway connected via eth0 network interface for example:
ip route add 192.168.1.0/24 dev eth0
or
ip route add 192.168.1.0/24 via 192.168.1.254

I'm trying to configure the network interface on embedded linux using ifconfig:
ifconfig eth0 192.168.0.101 netmask 255.255.255.0
but I don't know how to add the default gateway as an ifconfig parameter,
Any Ideas?
