Multiple IPs and Gateway

[ather_36]

Salam to all,
How can we define Multiple IPs and Gateway IPs to a Single Ethernet card.Suppose I have two different subnet IPs Address with Gateway.So please Kindly let me the command to define the multiple IPs and Gateway.
Suppose I have Two Different IPs:-
IP:192.168.1.1 Subnet Mask:255.255.255.0 Gateway 192.168.1.10

IP:202.251.150.5 Subnet Mask 255.255.255.0 Gateway 202.251.150.1

Plz help me
Thanks & Regards

Dear ather_36,
Salam,

Route command will help you. You must read the manual of route command.

# man route
# route add -net 192.168.1.1 netmask 255.255.255.0 gw 192.168.1.10
# route add -net 202.251.150.5 netmask 255.255.255.0 gw 202.251.150.1

P.S: I do not ask you this publicly but i have no other choice, i am still waiting for you to return my Book. When i will get my Book back ?

Best Regards.

I did it in this way :
route add -net 10.0.40.0 netmask 255.255.255.0 dev eth1
route add -net 192.168.100.0 netmask 255.255.255.0 dev eth1

What is the problem now ?

How can one single ethernet be on two different subnets.Do you have the multiport ethernet.Or If you can anyways define it you canot use multiple routers at the sametime.

Dear abdul_mateen,
Salam,

I believe you should read the manuals. I have not done this before so i can not tell you exactly.

# man ifconfig
# man route
# man ip

Best Regards.

You can achieve this task by giving some commands through ifconfig.I think you are asking for ipaliasing.Suppose you have a ethernet card eth0 and you want two ip's for this.you can do it with the following command:

ifconfig eth0 192.168.0.1 netmask 255.255.255.0 up

and you can give the other ip for this ethernet card like this

ifconfig eth0:0 192.168.0.2 netmask 255.255.255.0 up
