Setting up DHCP Failover

[Gregory Sloop]

Holy smokes.  The second you say that, and I look at my config I see I missed declaring peer port... wow, I have looked at this for almost a week and for the life of me could not figure it out.  Consider hand slapped to forehead, and that's what fixed it.

Thanks!

You need a "port" which is the port this DHCP server uses to listen for peer updates, AND [missing] a 
"peer port" which is what the other peer will use to listen.

My guess is, they won't talk because you haven't configured the port/peer port directives properly.
[At least that's what jumps out at me.]

It seems to me that there were problems/bugs with 4.1 and failover. [I seem to recall seeing posts on-list about it, but don't wager large sums of money on it...]
There are also some very nice features in 4.2.4+ {IIRC] versions that make failover work better in quite a number of situations. [A couple of new options]

You might consider using something 4.2+.
