VPNC-Nortel for Mac OS X (10.7)

I always wanted to connect my MacBook Pro to my University network using VPN when I am not in the University. But the Apani Nortel Contivity VPN Clients provided by my University are compatible only until Mac OS X 10.4. So I installed an open-source VPN Client for this. Luckily I found a detailed instructions for installing VPNC-Nortel for Mac OS X in this website. I followed those instructions with some modifications until I have a working VPN connection. And it works like a charm.

Here are my steps:

1. Install Xcode 4 from Mac App Store.
2. Install MacPorts.
3. Follow the steps written here.
4. When I compile the software, I got this error message:

   /usr/include/stdio.h:449: error: previous declaration of ‘getline’ was here
   make: *** [sysdep.o] Error 1

5. So I added this line:

   #define HAVE_GETLINE 1

   to #if defined(__APPLE__) section in sysdep.h to correct the issue.

6. After the compilation finished without error:

   sudo cp vpnc /usr/sbin/
   sudo cp vpnc-disconnect /usr/sbin/

7. Soon after I run the program, it was terminated by dead peer detection. So I run it with this command:

   sudo vpnc --dpd-idle 0

8. To disconnect:

   sudo vpnc-disconnect

Here is my configuration file:

Vendor nortel
kernel ipsec
IPSec gateway my_university_vpn_server
Local Port 45000
IKE Authmode gpassword
IKE DH group dh2
IPSec ID my_group_name
