[pptp-server] subnet gateway problem

[George Vieira]

Use tcpdump to see what's going on... you need to check all things like
 
tcpdump
netstat -rn
ifconfig
 
etc.etc.
 
use tcpdump to see if pings are coming through then check that ip_forward is
on!
 
echo 1 > /proc/net/.......something.../ip_forward
 
depending on our distro...

IIRC, this is normal.  Try adding proxyarp to your ppp/options file or your 
pptpd.conf file.
