You can assign a second address (alias) to your existing interface. |
| 15 |
It will be named eth0:X and can have any address you wish |
| 16 |
|
| 17 |
Gentoos /etc/conf.d/net has that possibility already built in, just ad a |
| 18 |
second line to your existing setup like so: |
| 19 |
|
| 20 |
config_eth0=( |
| 21 |
"84.115.XXX.XXX netmask 255.255.255.0" |
| 22 |
"192.168.1.1 netmask 255.255.255.0" |
| 23 |
) |
| 24 |
|
| 25 |
and restart networking. |
| 26 |
|
| 27 |
Minor drawback though: you cannot address the aliased interface with |
| 28 |
iptables, iptables -i/-o will only take the physical network device. |
| 29 |
Filtering via IP still works though. |
| 30 |
|
| 31 |
The other possibility is to use the dummy module (config option |
| 32 |
CONFIG_DUMMY=m under Device drivers -> Network device support) |
| 33 |
which will create as many virtual networking interfaces as you want, |
| 34 |
called dummy0, dummy1 ... |
| 35 |
(modprobe dummy numdummies=N, ifconfig dummy) |
| 36 |
