I kept trying and trying to figure out why I could not get my tunnel up at tunnelbroker.net
- Cable/Internet Router? scientific atlanta DPC2434 (cisco)
- Windows 7 Firewall?
- AVG anti-virus?
Finally, I found gogonet (on this forum Thanks). I downloaded the client. PRESTO! Up and running without any changes in configurations. Just added the tunneling client.
If TunnelBrokers or HE would provide something similar, I would change over immediately. Frankly, it is a pain to troubleshoot my ISP/router. Also, I don't like punching security pinholes in my current setup. Should not be necessary.
Onward towards the certifications.
