IPsec fails with sendto error

[Transeau]

I'm not sure what's going on - I haven't been able to get IPSec  up on any of the RCs.  Here's the tail of my log:

Aug 10 13:42:53	racoon: DEBUG: 260 bytes from 66.215.xxx.xxx[500] to 71.116.xxx.xxx[500]

Any ideals? (and Yes, I have an IPSec rule allowing traffic)
