wrong real server ip in connection

Hello!

First of all - Sorry, if wrong maillist.
I come up with strange situation and i dont really know, if its by
design or something is wrong in my configuration. so pls help)

i have three node self-balancing keepalived cluster for smtp.

server1 195.111.111.164 195.111.111.168
server2 195.111.111.165 195.111.111.169
server3 195.111.111.166 195.111.111.170

two vip address 195.111.111.177 and 195.111.111.176

problem:

when i do "telnet 195.111.111.176 25" i got balanced to address
from "virtual_server 195.111.111.176" group .164 .165 .166(i can see in
mail server log, which ip i am connected to). It ok, correct.

but with "telnet 195.111.111.177 25", i am expecting to see in
mail log, that connection goes to ip .168 or .169. or 170. But they,
somehow, again goes to .164 .165 .166. Is it correct behavior? I wish
it is not. Any ideas how to fix?

two vrrp instaces:

vrrp_instance VI_domain1 {
    state MASTER
    interface eth3
    lvs_sync_daemon_inteface eth3
    virtual_router_id 101
    priority 200
    advert_int 2
    virtual_ipaddress {
        195.111.111.176/27 dev bond0
    }
}

vrrp_instance VI_domain2 {
    state MASTER
    interface eth3
    lvs_sync_daemon_inteface eth3
    virtual_router_id 102
    priority 200
    advert_int 2
    virtual_ipaddress {
        195.111.1111.177/27 dev bond0
    }
}
