The VPN only stays up for a few minutes at a time. During those few minutes, it works perfectly, but suddenly the vpnc process just disappears. Previously, VPN has always worked perfectly for me: from home, from homes of friends and family, from every other hotel I have used in my travels around the world (including hotels with free Internet service provided by iBAHN), etc. But this is the first time I am using a Boingo id over iBAHN.
For VPN, my employer uses Cisco VPN, to which I connect with the vpnc client on a 64-bit Ubuntu 13.04. Since my employer has a proxy server that requires a login with AD credentials, all my desktop programs are configured to use a local cntlm as a proxy. I have two cntlm configuration files, and when I connect to the VPN or disconnect from it, I shutdown the cntlm process and restart it with the appropriate configuration file. This works like a charm, and the additional microscopic delay of going through cntlm is compensated for by the simplicity of the setup.
So, literally, this is first time I am having any major problem with my VPN setup, and I am not sure even where to start looking.
The only think I can think of doing is to play with the IP routing tables so that when I am connected over the VPN, I only route traffic to the company Intranet over the VPN, and route to all other addresses directly, bypassing the VPN. While configuring IP routing tables would be a good thing to learn, it would not help me get my job done any faster.
Suggestions appreciated. Thank you very much.
