OT: MLPPP upgrade = No IPSec VPN (weird issue)

Hi all,

Last night, we upgraded our Internet circuit to 2xT1 MLPPP. 
Before, all was
well in the land of IPSec and everything worked great.  Now,
I can get the
tunnels to connect successfully, but (and here's the weird
part) traffic only
passes if it's *above* 35 bytes!  If any traffic you are
sending from either
side does not equal at least 35 bytes when it goes out onto
the Multilink
interface, it is dropped.  As soon as you increase the
packet size to at
least
35, the traffic processes normally.

Anyone have any thoughts as to what's going on?  I'm at a
total loss here
(and
I like to think I know a bit about IPSec tunnels)...

Thanks in advance!
Aaron
