Oh dear god!  You're probably about to run into the same problem we had 
then.
The DrayTek 2800 series (specifically the 2820s), seem to have a nasty 
firmware bug that causes outbound ESP packets to go walkabouts somewhere 
in the router, especially if you're doing any kind of NAT with it.
If you find a solution, I'd love to know what you need to do.  We found 
that a Netgear DG834 works great for testing purposes!
Just a word of warning.
