At least I think it is.

Running Mandriva 2007.1, uname -a:
Linux ezcool 2.6.17-14mdvcustom #1 Sun Jul 1 17:50:58 CEST 2007 i686 AMD Athlon(tm) 64 Processor 4000+ GNU/Linux

and using pptpconfig to set up a VPN with a client's Windows Server. The VPN appears to be set up correctly, in that pptpconfig reports:
CHAP authentication succeeded
but I cannot ping the address given to the server 192.168.0.117 or anything on the VPN.

My routing prior to the VPN set up was:

Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.100.0 0.0.0.0 255.255.255.0 U 35 0 0 ra0
169.254.0.0 0.0.0.0 255.255.0.0 U 35 0 0 ra0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.100.254 0.0.0.0 UG 35 0 0 ra0

and after is:

Destination Gateway Genmask Flags Metric Ref Use Iface
217.46.123.123 192.168.100.254 255.255.255.255 UGH 0 0 0 ra0

0.0.0.0 192.168.100.254 0.0.0.0 UG 35 0 0 ra0

This all used to work, but I have not used it for some time, so I am obviously doing something wrong, but what?

All the best
