[pptp-server] Win VPN clients behind RedHat6.2 firewall connections to WinNT4 VPN server fails

[Steve Westerhouse]

I applied the VPN masq 2.2.14 patch to the source tree, created a .config
file and attempted to build the kernel.  Compilation fails with the
following messages.


gcc -D__KERNEL__ -I/usr/src/linux/include -Wall -Wstrict-prototypes -O2 -fom

The patch log file indicates that everything patched ok.  Is there an error
in the patch itself?

RedHat6.2 to perform the NAT functions using ipchains.  It appears that the
Windows clients connect but don't authenticate.  The connections timeout
with error 721 (Remote computer not responding).  I can ping the remote VPN
server from our internal network.
