I'm afraid I don't understand what I'm doing enough to know where to go. Apparently netfilter.org has a patch that allows multiple PPTP clients to route out to the same external IP (see http://www.netfilter.org/patch-o-matic/pom-extra.html,
under "PPTP connection tracking and NAT helper"). This says "Status: Testing, especially the 2.6.x port."
Can someone explain what Patch-O-Matic is, and how I would use it to install this PPTP connection tracking patch? I take it from the fact that it's in testing for the 2.6.x port that I shouldn't expect my Mandrake 10.1 distro to already have this installed. I've looked at the Patch-O-Matic documentation but don't know if I need to use Patch-O-Matic, or Patch-O-Matic NG (or what the difference is).
Can someone hand-hold me through this process? I will be eternally grateful. Cheers!
