[c-nsp] remote access vpn question

Hi,
I'm sure I'm missing something obvious here.
I have a pix 506e running 6.3.(5)

I have set it up to do remote access using ike mode config.
The inside int of the pix is connected to a dedicated 2960g for this client,
on which both their public and private vlans live. Server are connected to same
switch as pix, and inside int of pix is in same vlan as private ints of
servers.

i have set the ip pool to the private network of the client.
(10.10.1.0/24) NET-A
and the inside int of the pix is numbered into 10.100.1.0/24, which is pretty
much an arbitrary network assignment, NET-B

I have set up the acl to allow traffic from inside int(NET-B)  net to the 
ip pool (NET-A).

I have done this essentially mirroring all the config examples I have found.

It isn't working currently, it appears to be assigning the ip correctly to
client (from NET-A), but not passing traffic through to servers behind the
pix numbered into the same network.

Does the net that the inside int is in need to exist somewhere other than
on the pix? (given that the traffic from pix is going to have a source-ip of
the pool, i don't know why it would.)

I'm sure i'm missing something obvious here, and its driving me a little nuts.
any help is appreciated.

my config is below:

Thanks,
Dalton
