Dear netfilter developers, I am using linux 2.6.14.3 kernel with ip_nat_pptp compiled as a module. I have discovered a bug in this condition: I have installed pptpd on a firewall. Assume the firewall has the follow IP: (external) 1.2.3.4 (internal) 192.168.0.1. The pptpd is serving as a VPN for 192.168.0.0/24. If I am using a VPN client (assume it has IP address 192.168.0.2) to connect to 1.2.3.4, it will generate a kernel panic. (Of course, people normally don't do such stupid things, but they may make a mistake, since my customers are roaming between sites and may choose the wrong VPN connection and then crashes the firewall.) I understand this is a really a abnormal test case becasue no one would VPN to their own servers if they are inside the company. Thank you.
