The PPTP connection tracking works for both clients and servers,
since after all, you need one of each to make a PPTP connection.
While you can get by without it for DNAT to a server, the PPTP
connection tracking allows you to automatically NAT the related
GRE connections, and you can use a conntrack state match to only
allow related GRE packets through the firewall.
