I was running M0n0 1.11 on both ends of my tunnel.  But everytime I
shut the power off at my house (doing electrical work) the IPSEC
connection wouldn't work again, until I turned IPSEC off and then back
on.

I heard of the option to prefer old IPSEC SA's in the new beta and
decided to try it on my home m0n0, leaving my work m0n0 at 1.11.

Now when I turn the power back on at home, the IPSEC tunnel comes
backup, but with severe packet loss.  Here is what it looks like:
