Hello everyone, I'm new the the forums but I think I found the right place to put this.  I'm losing my mind with this set up - if you have VPN on your mac setup and can offer any kind of advice, Its greatly appreciated:


As of now when I test VPN on my iPhone 5 over 3/4G...it says connecting...authenticating...and then that I've been disconnected..




1) iMac (running the OSX server App , Mountain Lion v10.8.2)


2) iPhon 5


3) MacBook Air


4) Airport express new model (looks like a while apple tv)




1) Connect external hard drive to iMac, run the server, and allow access to files via VPN to MBA / phone


2) Create a secure network for browsing



OK so starting with the airport -


Router Mode: DHCP & NAT

DHCP Range: to

DHCP reservations: Server is at (static...right?)

                               MBA is at (static...right?)


Port Settings: Screen Sharing


                     File Sharing


All ports are good and open (VPN has UDP 500,1700, and 4500 open and TCP 1723 open.  The private IP address is, same as static above)


Connection Type: DHCP

IPv4 Address: 68.53.162.XXX

Router Address: 68.53.162.X

Domain Name: some website from comcast



Ok now on the server:


Server Pane - Network


Host name:  XXXX.server.private

Interfaces: WIFI connection at IP


DNS Pane


Host Names: XXXX.server.private



VPN Pane:


Configure VPN for L2TP

VPN Host Name: 68.53.162.XXX (routers IP address..green light is on)

Shared Secret: XXXXXX

Client Addresses 31 for L2TP

DNS Settings: 1 Server, 1 domain.  (server is , server static IP)

Routes: No routes configured.



Now...I go to my iphone 5...


Server: 68.53.162.XXX ( I'm asking it to sign into my router, is this correct?)


all other information inputed correctly, proxy is off, send all traffic is on.




what am I doing wrong? this has to be a simple fix? should I be using my routers IP ending in 1 digit? or the IPv4 address ending in 3?


Any help would be appreciated , thanks so much

OS X Mountain Lion (10.8.2)
