Backup thinks it's the Master
I have been running a pfSense Server for some time now and finally decided it was time to add a second for failover. I set everything up and the Synchronization worked great. All my firewall rules, Virtual IPs, and settings moved over great. However, when I go to CARP status on each server they both say they are master.
Both servers are identical Dell 850 rack mount servers with 3 interfaces.
I am running 1.2.RC3 on both servers as well as haProxy for load-balancing.
On Server 1 I checked every box for synchronization and entered the IP for Server 2 to sync to.
On Server 2 I only checked to enable synchronization.
I have the boxes connected via a dedicated 10/100 interface through a crossover cable.
On Server 1 the Virtual IPs have an advertising frequency of 0.
On Server 2 the Virtual IPs have an advertising frequency of 100.
I have a firewall rule on the SYNC interface on both servers to allow all traffic.
I did at one point see an error scrolling at the top saying something about Error Code 2 Invalid Payload Received or something similar. However I don't see this error anymore.
Any idea what might be causing this. I know it should work, I have the same exact setup as a colleague of mine and his had been working for a long time. The only difference is he is running 1.2.RC1.
I just seen there was another topic discussing this same problem already. Sorry :-[
Anyway, do you think this update will fix my issue? My install disk was made about 2 weeks ago from 1.2.RC3:

I just commited some fixes for this. Please install a snapshot from http://snapshots.pfsense.com/FreeBSD6/RELENG_1_2/updates/ in 2-3 hours from now.
I did a firmware update to that shapshot and it did not fix the issue.
I found the problem.
The WAN interface on Server 2 was plugged into the wrong VLAN on the switch. Not sure why that would cause this problem, but all is working as it should now.
