L2TP VPN and Back to My Mac
Can someone please confirm there is a conflict with the OS X Lion Server L2TP VPN and the Back to My Mac service.
I'm getting IKE packet errors on our VPN server and suspect someone on the network has Back to My Mac enabled.
Feb 14 12:12:12 server racoon[196]: IKE Packet: receive failed. (Responder, Quick-Mode Message 1).
"Authentication Failed" from the client side. But after a few attempts it will connect... strange.
IPv4 IPv6 issues?
My router is non-Apple
and has the following NAT entries forwared to the Mac Server for the L2TP VPN
UDP 500
UDP 1701
UDP 4500
it also has UPNP enabled.
Does Back to My Mac use UPNP, IPv4, or IPv6 only?
Is Back to My Mac conflicting with the VPN service in Lion Server?
If so, WHY is this not documented?
Mac mini, Mac OS X (10.7.3), Lion Server (10.7.3)
