I have not used the pc300 card, but I have used LRP in the past and had
excellent results. Since LRP uses a standard linux 2.2.x kernel you will
need to apply the VPN masq patches to add MASQ VPN support. i.e.
ip_masq_pptp.o

Thats a good question. In fact, I asked the same question when I setup the
RT-314. Somehow, this box "magically" handles masquerading protocol 47 (GRE)
packets when you configure port 1723 to be forwarded to an internal IP
address. 

FWIW: I installed a SonicWall firewall ( www.sonicwall.com ) a few weeks ago
and its MASQ PPTP configuration was the same. I only forwarded port 1723 to
an internal PTP server. It handled protocol 47 behind the scenes.
