shows the steps for the case where your internal networks overlap with the other network. If the other side does -not- overlap with you, you can just leave out some parts of what I showed there.

i just need to map my inside block to a new private block, so if i understand correctly, i just need to.

static(inside,outside) newprvtnet mask existingprvtblocknet mask

access-list vpn_acl permit ip newprvtnet mask vpnpeernet mask

and add, newprvtnet mask, to the nat 0 acl
