On a debian squeeze server I got 2 IPs on eth0 (eth0 and eth0:1). When opening TCP connections the server uses the eth0:1 IP by default. However I want it to use the primary (eth0) IP because I want the other to be used for (listening) daemons only.
#/etc/network/interfaces
auto eth0
iface eth0 inet static
address 92.xxx.xxx.92
netmask 255.255.255.192
network 92.xxx.xxx.64
broadcast 93.xxx.xxx.127
gateway 92.xxx.xxx.65
auto eth0:1
iface eth0:1 inet static
address 108.xxx.xxx.146
netmask 255.255.255.192
gateway 108.xxx.xxx.129
#ip route show
108.xxx.xxx.128/26 dev eth0 proto kernel scope link src 108.xxx.xxx.146
92.xxx.xxx.64/26 dev eth0 proto kernel scope link src 92.xxx.xxx.92
default via 108.xxx.xxx.129 dev eth0 src 108.xxx.xxx.146
default via 92.xxx.xxx.65 dev eth0
What can I do to make debian use the 92. IP for outgoing connections? The other one should still work of course.
/etc/network/interfaces
. everything else was done by debian installation.
