yes--if your are performing SNAT/MASQ for your entire internal network
on your gateway, it won't work.  there is a PPTP conntrack and nat module
in POM for this situation, but it will only compile against a 2.4 kernel.

one option would be to give the PPTP client a dedicated public IP and
perform a one-to-one SNAT/DNAT for that client and allow TCP 1723 and
IP protocol 47 outbound from that client and IP protocol 47 inbound to
that client from the PPTP server.
