You want only my keepalived.conf ?

Well I could not find anything that would have confirmed my suggestion.

Anything like

"block { config value }" in one line caused weird errors in my tests with keepalived so I just wanted to make sure.

Does this "ping-pong" situation end after those 8 mentioned steps or does it continue? Do you see the appropriate vrrp packets on the specified interface on master and slave?

I'd suggest reducing your config to one VIP, add appropriate values for broadcast and interface to the virtual_ipaddress block (see example below 1),disable shorewall to make sure it is not the problem and then look for packets with tcpdump (see below 2)

1
virtual_ipaddress {
        10.2.20.20/24 brd 10.2.20.255 dev eth0
    }

2
tcpdump -i eth net 224.0.0.0/8

You should be able to see the virtual router id and the priority for each packet so you can see which machine sees which packets on which interface.
