Bad news I'm afraid! There are lots of reports of issues with the VPN server in OS X Mavericks. I advise anyone who relies on their VPN server to not upgrade to OS X Mavericks just yet.
There are several discussions on Apple's support forums about it. If you've already upgraded to Mavericks and are having problems, check out some of the discussions below. You never know, there may be a suggested fix that works for you.
This may not apply to everyone, but I've found that rebooting my router temporarily solves some of these issues. All we can do now is wait for Apple to release an update that addresses this bug. Hopefully it will be soon!
