I would strongly suggest that you abandon using PPTP altogether. I'm not kidding. If a VPN protocol is unable to provide you with meaningful security, then what's the point of using it? Bruce Schneier with Mudge of L0pht showed a while ago how worthless MS-PPTP is as a VPN protocol:
http://www.schneier.com/pptp.html As they put it: 3. How bad is it? Very. Microsoft PPTP is very broken, and there's no real way to fix it without taking the whole thing down and starting over. This isn't just one problem, but six different problems, any one of which breaks the protocol. 4. Doesn't Microsoft know better? You'd think they would. The mistakes they made are not subtle; they're "kindergarten cryptographer" mistakes. The encryption is used in a way that completely negates its effectiveness. The documentation claims 128-bit keys, even though nothing remotely close to that key length is actually used. Passwords are protected by hash functions so badly that most can be easily recovered. And the control channel is so sloppily designed that anyone can cause a Microsoft PPTP server to go belly up. There is full support for IPsec in all modern versions of Windows, and in particular the versions of Windows that you are using, and I personally believe that it is the best thing that ever happened to you that you're having trouble getting it to work! Get FreeS/WAN or OpenSWAN or the inherent 2.6.x IPsec implementation for IPsec on Linux. FreeS/WAN to Microsoft IPsec interoperability is fairly well documented as well. As of now, it seems that for VPN's it's either IPsec or nothing. IPsec seems to be too complicated, but it's a fair sight better than any of the many, horribly broken protocols out there. -- Philippine Linux Users' Group (PLUG) Mailing List [EMAIL PROTECTED] (#PLUG @ irc.free.net.ph) Official Website: http://plug.linux.org.ph Searchable Archives: http://marc.free.net.ph .
