Hi there, I'm trying to get PoPToP (http://www.poptop.org) working on a Fedora Core 1 box, but because this machine is behind a firewall I need to enable VPN masquerading so that outbound GRE packets are handled correctly. According to the VPN Masquerading HOWTO document http://www.ibiblio.org/pub/Linux/docs/HOWTO/VPN-Masquerade-HOWTO I need to install the VPN Masquerade kernel patch, but the only links I can find are from this site http://www.impsec.org/linux/masquerade/ip_masq_vpn.html which only has patches up to the 2.4.19 kernel. My (hopefully) simple question is this: where can I get the VPN Masquerade kernel patch for Fedora Core 1 2.4.22-1.2115.nptl? Apparently once applied it's merely a case of enabling PPTP masquerading in the IPFilter section when configuring the kernel. If anyone has any experience of this, and can help me in any way, I would be most grateful. I'm now getting to the pulling hair out stage on this :-) Thanks very much, Andrew Hall.
