OS X Server 3.0.1 VPN inconsistent
I understand that many people have had trouble using their VPN Server since the 3.0 Server update with Mavericks. I have NOT had trouble connecting my iMac (OS X 10.9 Mavericks) to the VPN Server here at work (Server 3.0.1, OS X 10.9 Mavericks), or connecting my iPhone to the VPN Sever here locally (but not from anywhere else over Wifi or LTE). However I cannot connect anything else to the VPN Server. I cannot connect my MacBook Pro to the VPN even when on the local network here at work, though my iPhone will. I was even able to connect my Macbook Pro here at work to my iMac at home via Screen Sharing and then connect to the VPN with my iMac at home to the VPN Sever here at work. Obviously Back to My Mac works. I DID disable Back to My Mac here on the MacBook Pro when trying to connect to the VPN Server here on the local network to be sure that Back to My Mac wasn't interferring. Back to My Mac is running on my iMac at home and it connects to the VPN Server here just fine.
Is there an issue with the VPN server not liking similar subnets on both ends of the connection? Would that affect trying to connect locally? (I understand that connecting locally isn't necessary and redundant, I just do it for testing the authentication settings, etc.)
Why would my iMac connect from home, but not my MacBook Pro locally? Why would my iPhone connect locally, but not from home? Why is it reported that Back to My Mac will cause VPN not to work, when in my case it makes no difference. I have checked the authentication settings and the IP addresses on all the devices. I have also replaced racoon in /usr/sbin/ with the version from OS X 10.8 Mountain Lion. Replacing racoon had no effect on the ability or lack thereof to connect.
