[gentoo-user] Network problem with linux server

Hi All.

This problem is not strictly related to gentoo, however I'm sure someone
here will be able to help me in some way: sorry if I bother you!

I'm having a really strange problem: for some reason, everytime I reboot my
server, the default gateway gets attached to the 'lo' interface, even if I
correctly attached it to the eth0 device.

I fixed the problem editing the /etc/sysconfig/network file and adding

GATEWAY5.75.145.1
GATEWAYDEV=eth0

however I'm not sure this is the solution: I already configured the default
gateway only in the ifcfg-eth0 file!

After this, I have an even worse problem: doing an ssh 195.75.145.1, I get
an answer from my own server like if it was a loopback address !

Here is the output of ifconfig:

eth0 Link encap:Ethernet HWaddr 5C:F3:FC:55:63:42

lo:0 Link encap:Local Loopback
inet addr:195.75.145.120 Mask:255.255.255.0
UP LOOPBACK RUNNING MTU:16436 Metric:1

here is the output of ip route

192.168.19.0/24 dev eth2 proto kernel scope link src 192.168.19.95
195.75.145.0/24 dev eth0 proto kernel scope link src 195.75.145.122
169.254.0.0/16 dev eth0 scope link metric 1002
169.254.0.0/16 dev eth2 scope link metric 1004
default via 195.75.145.1 dev eth0

Please!! Do you have any advice?

Thanks,
Massimiliano
