All, I've been trying to ugprade my router/AP running 2.4.19 to 2.4.21. With 2.4.19 I was running Brian Kuschak's PPTP patch. With 2.4.21 I've tried both the newnat patch from http://roeder.goe.net/~koepi/newnat.html and the pptp patches in patch-o-matic-20030630. Both apply cleanly and compile without errors. Both work and allow the client to sucessfully make and use a PPTP connection. The problem comes that when the PPTP connection is terminated, the masq machine completely hard-locks. I can't ping it from any machine as soon as I terminate my PPTP connection on my client. I believe the kernel is Oops'ing, although I don't have a console on it to verify. I'll try to get a serial console setup in the morning to verify. The machine is an AMD Duron 800Mhz. The kernel was compiled with gcc 2.95.3. The kernel was a stock 2.4.21 kernel with either the newnat patches or the patch-o-matic patches. The only other patch applied was a patch to upgrade the wireless extensions support from 15 to 16. I can try removing this patch, although I don't believe it is the cause of the problem, since I'm not even using an 802.11b machine to establish the PPTP connection. The PPTP client was a Windows Server 2003 machine, and the PPTP server was a Cisco 3030 VPN Concentrator, if that helps at all. Thanks! -Dustin
