Decomplicate things a bit:

1. Remove the VRRP authentication completely (if you feel you can).
2. You only have a single VRRP instance; you don't need a vrrp_sync_group. Comment it out.

Start the one assumed to be MASTER.

On the server assumed to be BACKUP, use tcpdump to make sure you can see the announcements - "tcpdump -qn net" should see you on your way with this. If you can, make sure that you don't have iptables rules sitting there getting in the way of them.

Also, as you don't describe your environment, make sure nobody else on the same network is doing VRRP. If they are, think about your inter-server communication by considering putting the announcements on a private or protected network instead.
