PPTP Server dead since 374.41 upgrade

[EdisonW]

Hello all,

I've noticed my N66U's PPTP server no longer allows any connections since upgrading it to 374.41.

Here's one of my log entries:

May 12 12:04:37 pptpd[514]: CTRL: Client xxx.xxx.xxx.xxx control connection finished

I haven't changed any settings on my clients, iOS 7.1.1, OS X 10.9.2, and Windows 8.1 Update 1 devices since the upgrade.

Any ideas on this one?

Cheers

Unfortunately nothing mentioned in change log for PPTP in the new version:

Media Server page.
- FIXED: Pass correct valid and preferred lifetime to radvd when
using DHCPv6-PD (Patch by pinwing)

to the time shift caused by NTP at boot time
(Patch by pinwing)
- FIXED: Various IPv6 connectivity issues related to services
being (re)started at the wrong time, or twice.
(Patch by pinwing)
- FIXED: Build system would sometime try to use the local system's
header/libs - use a pkg-config wrapper to avoid this
