Masq'ing pptp

I've got 6.4 (kernel v 2.2.14) running on my masq box, and wish to run a pptp VPN through the masq/fw to someone on the farside of the i'net. My masq successfully works with everything else so far. I've been reading at ftp://ftp.rubyriver.com/pub/jhardin/masquerade/ip_masq_vpn.html ftp://ftp.rubyriver.com/pub/jhardin/masquerade/VPN-howto/VPN-Masquerade-2.ht ml http://members.home.net/ipmasq/ but I'm not sure of the SuSE kernel status. Do I need to apply the patches they recommend, or does perhaps SuSE have those in? Could I get/make the module and insmod it? TIA Kevin
