can you guys please guide what is going on . in old Debian version i
do this with no problem sub interfaces were very easy task. but here i
invest the whole day.
I must say I have run into many problems on my own machine but never
this one.
Are you sure your gateway recognises your secondary IP?
I even have 2 IPs on such an alias and they all work fine:
iface eth0 inet manual
pre-up ip link set eth0 up
iface eth0:0 inet dhcp
iface eth0:1 inet static
address 149.x.x.127
netmask 255.255.255.0
In my case I do additional routing:
ip rule add from 149.x.x.127 (that's the secondary) lookup 2
ip route add default via 149.x.x.1 (gateway address for the second IP)
table 2
