Thanks to those who responded to this email. What i did actually is; 1. patched the kernel with ip_pptp_* P.O.M. (KERNEL_DIR=/usr/src/linux ./runme bla bla bla) 2. recompile iptables (source) 3. recompile the kernel (make menuconfig; make dep; make bzImage, make modules; make modules_install) 4. reboot machine viola! works like a charm. cheers! ----- Original Message ----- From: "Filip Sneppe" <filip.sneppe@xxxxxxxxx> To: "John Paul" <john@xxxxxxxxxxxxxxxxxxxx> Cc: "George Vieira" <georgev@xxxxxxxxxxxxxxxxxxxxxx>; "Esteban" <esteban@xxxxxxxxx>; <netfilter@xxxxxxxxxxxxxxxxxxx> Sent: Wednesday, June 04, 2003 4:17 PM Subject: Re: Nat problem with GRE > On Wed, 2003-06-04 at 02:10, John Paul wrote: > > George, et al. > > > > I actually have the same problem.
