Hey,
The issue with PPTP on the WAN side (at least as experienced with my
ISP) is that when the tunnel disconnects or times-out,
if the keep-alive option is set to true the pppd process would fire up
another instance of the pptp connection script to bring up
the tunnel again, although it seems that there is a conflict since (if
debugging log is enabled) it is shown that the pptp client
is timing-out on LCP connection requests.
For this reason I have added a script to /etc/ppp/ip-down.d/ to kill
all connections, and if keep-alive option is set to true
then to bring up the wan interface again.
I have written it just a couple of minutes ago so it hasn't been
tested but I am guessing the syntax is the only issue
with it, if any so please review and apply the patch for the next build.

config_load network
config_get proto wan proto
if [ "$proto" = "pptp" ]; then
killall pptp;
killall pppd;
kill -9 `cat /var/run/ppp0.pid`;
fi
config_get redial wan ppp_redial
if [ "$redial" = "persist" ]; then
/sbin/ifup wan;
fi
Jeremy, I'd appreciate if you could push this to SVN, thanks.

Liran Tal.
