I used to use a switch plugged into my dsl modem to hook up

So I have plugged my laptop into the 4-port(sis[0-3]) ethernet card
in my desktop and now have an ip address(192.168.1.32) assigned
to the laptop by dhcpd running on the desktop.

I also have net.inet.ip.forwarding=1 on the desktop.

I assume I need to add some rules to the laptop routing table
and to update the pf.conf rules on the desktop with a NAT rule.

What rule(s) do I need to add to pf.conf to give the laptop internet
access via the desktop?

dhcpd will likely tell your laptop to use your desktop as default
gateway; this is all that's needed to make the routing table on the
laptop work in the most common case.

As to your second question, see the PF User's Guide - it even has an
example detailing pretty much this scenario. It can be found at
