I am in the process of getting 5 VMs running on my laptop to run for SP2013. Normally I work off of my WiFi adaptor so i decided to see about connecting both my WiFi and my wired adaptors to the VPNs. Tothat end I followed a very simple blog post a very simple blog post by Rick Gipson to set this up.
Summary is that you share your WiFi adaptor and add a new Internal network on a second network adaptor to all of you VMs. You can read his post for the details. I tried it and never quite got it to work, but I suspect that if I spend a bit more time at it…I would.
Fast forward to Monday AM and I rady to log into my Cisco VPN to get some work done for a client. Lo and behold I get an error connecting to my Cisco VPN. The error that I get? Secure VPN Connection terminated locally by the client. Reason 442: Failed to enable the Virtual Adaptor. Now, for any o fyou who are regular users of Windows 8 and Cisco you know this error. Its the first thing you fix after installing Windows 8. There are dozens ifnot hundreds of blog entries about how to resolve it. You open up RegEdit, you navigate to HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\CVirtA and you modify the Display Name to get rid of the extra characters so that it only says "Cisco Systems VPN Adpater for 64-bit Windows".
Easy as pie…except that I have already made that modification. Hmm. I did check in the registry to see if it had been changed…it had not. Then I remembered the shared WiFi adaptor. I went to the Network adaptor and I unshared it and voila! Everything works.
Not sure, why, but if you share your network adaptor, Cisco won’t bind a VPN to it. As I think about it it likley is because other computers could use that adaptor and the VPN might be compromised.
