Bug Alert: Network Connect VPN Client on OSX Yosemite

Doing some wireless troubleshooting, I came across a bug in Network Connect. Losing network connectivity (computer sleeps, lost wireless connection, etc) while connected to a VPN using Network Connect will effectively break your internet connectivity. You will still connect to a network and obtain an IP address but you won't access the web. If you ping google.com, you will get a "cannot allocate memory" message. The Network Connect will attempt to reconnect but will fail.

A couple fixes:

If you encounter the "cannot allocate memory" message when trying to ping a server, do one of the following to clear your route. 

• Reboot your computer
• On terminal, do a netstat -rn
• Get the IP address from the default gateway
• sudo route delete -host <ipaddress>
• Turn your wireless off and on

A better OS X VPN client would be Junos Pulse. This client requires a Junos Pulse account so you'll have to search the web for a free download. I found mine from Step 3 in Troubleshooting here http://iso.csusb.edu/download/vpn

This may be fixed with any upcoming Yosemite updates. It's been pretty buggy on release.
