Multiple Network Configuration in Linux

I have a Debian linux OS and use it in my office and in my home. The network configuration i use is using static configuration. I have problem with this, when i swicth from home to office network, the configuration is different, the routing also different.

Everytime I switch network, I have to open the configuration file in /etc/network/interfaces  and enable / disable configuration line.

So I do some research and found that we can create a multiple configuration in the interface file. so when we have let say 2 config called home and office, we switch the configuration by issuing this command :

#ifup eth0=home

#ifdown eth0=home

#ifup eth0=office

#ifdown eth0=office

So lets go with the example , file /etc/network/interfaces  :

auto lo

iface lo inet loopback



#home config

iface home inet static

   address 192.168.1.100

   netmask 255.255.255.0

   broadcast 192.168.1.255

   gateway 192.168.1.111

   dns-nameserver 8.8.8.8



#Office config

iface office inet static
  address 192.168.100.100

  netmask 255.255.255.0
  broadcast 192.168.100.255
  gateway 192.168.100.24
  dns-nameservers 8.8.8.8
  up route add -net 172.16.0.0 netmask 255.255.0.0 gw 192.168.100.99

With this config file we can just set the interface configuration to the one we need. Example when in office issue this command :

#ifup eth0=office

If in home, just issue :

#ifup eth0=home

With this configuration, we not need to touch the configuration files.

How about the GUI ? Well, i am a server guy, so command line is powerfull enough for me.
