Only when I connect to the corporate network I've got the access.

For example, when Internet Access is strictly locked down. When multiple network interfaces are connected, passive polling may fail on one or more of these.

Stanford's VPN allows you to connect to Stanford's network as if you were on campus, making access to restricted services possible. To connect to the VPN from your Windows computer you need to install the Cisco AnyConnect VPN client.

Find the service ‘Cisco AnyConnect Network Access Manager‘. 3 wheel forklift. Right click and stop the service. Now Cisco AnyConnect will say ‘NAM service unavailable‘ Now Windows will use the native WiFi client to connect to the WiFi; When you reboot your system, the NAM service will start and may cause problem again. Basically, the kill switch blocks your Internet connection once you get disconnected from a VPN server. This is beneficial if you do not want your real IP address to be disclosed when browsing the Internet. Some Window 10 users have stated that disabling the kill switch feature fixed their VPN blocks Internet connection problem.

Two types of VPN are available:

  • Default Stanford (split-tunnel). When using Stanford's VPN from home, we generally recommend using the Default Stanford split-tunnel VPN. This routes and encrypts all traffic going to Stanford sites and systems through the Stanford network as if you were on campus. All non-Stanford traffic proceeds to its destination directly.
  • Full Traffic (non-split-tunnel). This encrypts all internet traffic from your computer but may inadvertently block you from using resources on your local network, such as a networked printer at home. If you are traveling or using wi-fi in an untrusted location like a coffee shop or hotel, you may wish to encrypt all of your internet traffic through the Full Traffic non-split-tunnel VPN to provide an additional layer of security.

You can select the type of VPN you want to use each time you connect to the Stanford Public VPN.

Cisco Anyconnect Updates

I'm going to update my original post above, but I was able to (finally) resolve the issue and wanted to share the solution. Thanks to some Internet searching, I learned of some settings in the Frontier/Netgear DSL modem/routers that is (as far as I can tell) designed to aid in forwarding various services through the router/firewall. From there, I was able to track it to the 'ALG' setting in the Port Forwarding area of the modem/router firmware. Here's what I did:

Groupon bartending

  1. Login to the DSL modem/router via the web interface
  2. Click on 'Advanced' at the top menu
  3. Click on 'ALG' under the section to the left denoted by the red toolbox icon
  4. Remove the checkmark for IPSec and click 'Apply'
  5. Reboot the modem/router

After doing this, I was able to successfully connect using the Cisco VPN Client software- hope this helps the next poor soul that runs into this! Hopefully it will save you that many hours over many days of troubleshooting it took me..

EDIT: Additional note- my home DSL router/model is a Netgear 7550 model, while it appears that both of the employees were issued the (presumably newer) Netgear D2200D model. The VPN seemed to pass through the 7550 model without an issue, so this may be an issue that's model specific.
