Vista - Cannot connect to Cisco VPN from VPC

I'm new to the VPC world and I don't have much networking experience. My
host machine is Windows XP Pro/SP2 and my guest is Windows Server 2003.
Initially I was unable to connect to the internet on the guest, but resolved
the problem by changing the networking Adapter 1 to Shared networking (NAT)
and hardcoding the DNS on the guest to 192.168.131.254. This resolved the
internet connectivity problem, but I still cannot connect to the Cisco VPN.
The authentication window displays and I can enter my user/password, but the
connection never completes. The error is "the virtual adapter failed to
enable". I've tried changing my Adapter 1 to my host's network adapter, but
then I cannot access the internet and the Cisco VPN authentication window
never pops up.

Any help would be appreciated. Thanks.

Can't be done...
First you cannot use Shared Networking for tis.
Second Cisco VPN is very picky on the networks when it connects and
basically shuts down all networks other than its own VPN one.

I don't hink it can even be done if you have a properly configured
network for the guest (using the host NIC instead of Shared
networking).

What I know works is to connect a Microsoft VPN tunnel from a guest
using PPTP protocol, but ten PPTP does not sut down other
networking....

it has direct access to the local LAN and should work just the same way as
the host itself does.

You can most definitely use Cisco's VPN software in a virtual machine. I do
it all the time since their current version doesn't work in my host OS
(Server 2008 x64).

Concerning Cisco VPN
--------------------
Thanks for pointing out that local LAN access can be active. My Cisco
VPN was set up by the IT department and I never was able to access
anything else when the tunnel was connected. But now I found the entry
you refer to so I will try that.

Concerning VM usage
-------------------
Yes, if the VM has a NIC that is getting its own DHCP address via the
host NIC and out on the LAN then it is fine. But I doubt that the OP
situation using NAT will ever work....

It definitely can be done because I have co-workers who are successful with
it. We've compared configurations and the only difference is our ISP. I've
changed from Shared networking (NAT) to using my host's NIC and this makes it
worse - I can't connect to the internet or to the VPN. I already tried
re-installing the VPN client to no avail and I am running Cisco 5.0.02. Any
other thoughts from anyone? Thanks for the help.

news:A530EE03-5549-4D51-8509-5B47FD6E2864@xxxxxxYour situation is quite different from John Sheridan's. His host machine is
on a local LAN and the vm gets its network config from a local DHCP server
when he uses the physical NIC option for his vm.

If you are connecting directly to your ISP this will not work. Your host
has already connected to the ISP and established an Internet connection (and
received an IP from the ISP's DHCP server). The ISP will not issue an
additional public IP for your vm automatically. You may be able to persuade
them to do that for an additional fee!

Using the shared networking (NAT) option allows you to connect to the
Internet by sharing the host's Internet connection. The vm gets a private IP
address from the mini-DHCP server (similar to the situation with ICS).
Obviously the Cisco VPN client isn't happy running over this connection.

news:eXCnjhT6IHA.5116@xxxxxxGoogling "Cisco VPN" and "ICS" brings up many, many hits with the word
"incompatible" in the preview. I'd say it's a safe bet Cisco VPN won't work
with ICS.

The solution would be to get a router, which isn't worth it if you only have
one physical PC, or a second address from the ISP.

BTW, Lynne, who is your ISP, and is it cable or DSL?
