Subject: Bug report: ip_nat_pptp kernel panic
Date: Thu, 15 Dec 2005 17:58:37 +0800	[thread overview]
Message-ID: <43A13E4D.8040209@school.hk> (raw)

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.
