Specifically, all of the kernel versions (2.4.x, 2.2.x, and 2.0.x) support patches to allow for both ONE or MULTIPLE PPTP users behind a IPMASQ server to connect to the -same- PPTP server. The 2.4.x kernels currently have a PPTP module now in the newest versions of the IPTABLES program and there is another version available on the IPMASQ WWW site.
