Identical setup here once.  I couldn't get NAT going in three minutes, so
I moved on to another solution.

Internal network was 10.10.10.x, including laptop's wireless.  Laptop's
LAN and workstation were given 10.10.20.x IPs.  Workstation has default
route of 10.10.20.10 (laptop LAN).  Laptop had sysctl.forwarding=1 and
routed to NAT gateway.  Gateway had route for 10.10.20.x to laptop wi0 IP.

Worked just fine and didn't require extra work.
