Problem when using aliased interfaces on realservers

["Viperman" <viperman77@xxxxxxx>]

Hello there,

I'm running LVS with IP TUN pretty fine, but now when trying to do a new
thing, I can't get it going.

On the real server, if I do that

ifconfig tunl0 0.0.0.0 up
echo 1 > /proc/sys/net/ipv4/conf/all/hidden
echo 1 > /proc/sys/net/ipv4/conf/tunl0/hidden
ifconfig tunl0:0 VIP-1 netmask 255.255.255.255 up

it works fine, np at all

now, if I add another VIP, like this

ifconfig tunl0:1 VIP-2 netmask 255.255.255.255 up

it stops working.
I tried to add the routes like

route add -host VIP-1 dev tunl0:0
route add -host VIP-2 dev tunl0:1

but no luck.

Any guess? Am I missing something here?

Thanks for your attention.

Leni
