[pptp-server] what does this mean

[Vlad Strezhnev]

We had similar problem with pptpd server behind masquerading 
firewall.
The kernel on the firewall (2.2.17) was not patched with 
ip_masq_vpn.patch.
After we applied the patch the problem was gone.

Might look in Linux VPN Masquerade HOWTO: Patching and configuring 
kernel for VPN Masquerade support for details.
