Per,

        If I understand what you need, you want to look at IP masquerade on
'router/firewall' so misc. systems that connect to router/firewall can
masquerade as n.n.220.66 with all responses from the ADSL router side NAT'ed
back to misc. systems on n.n.220.64. I had to do something similar with:

provider
  |
  V
Cable/DSL router
  |  n.n.6.13
  |
  V
router/firewall
  |  n.n.6.17
  |  (connection via 'gulp' dial-up)
  V  n.n.5.15
router/firewall
  |
  |
  V  n.n.5.x/24
misc systems

        The key to making everything work was to set up IP masquerade with IP 
tables
on router/firewall (n.n.5.15)

        Sorry I can't provide the exact config, but the n.n.5.15 box is off 
right now
and 20 miles away at the lake :-(  Hope this helps.
