I have tested your configuration using v1.3.5 and ping 10.55.123.9 works for me. I suspect this is not a keepalived issue, since the address is being added to interface eth0.
I suggest you try this without using keepalived by executing ip addr add 10.55.123.9/24 dev eth0 and then seeing if the ping and telnet work.
You will probably need to check things like your firewall (iptables), routing etc. You might find wireshark/tcpdump helps you see what is happening. Tools like traceroute can help see where packets are being dropped.
