"Linux Host", "Windows guest": Cisco VPN routing problem

Postby rlbay » 20. Jul 2010, 17:38

Hi, I am writing here because after a major update of VirtualBox (I think from 3.1 to 3.2 but not sure), I am interested by a specific VPN connection problem.
This is the situation:
- host: Linux x86_64 (Ubuntu 10)
- guest: Windows XP SP3 32-bit

From Windows XP, I am connecting using Cisco VPN client using a bridged NIC. The connection is successful, but after that I am not able to use the remote lan.
What I can say is that:
1. ping remotehost fails
2. tracert -d remotehost fails as well since the first hop
3. the same Cisco VPN connection on a "real" XP machine, with almost the same configuration (patch level, installed software, ...), works fine (ping remotehost responds, tracert -d works, ...)
4. the same Cisco VPN connection on the same VBox Windows, guest worked fine some months ago
5. I tried to find a solution in different ways without solution:
- changed guest NIC from bridged to nat
- changed guest NIC emulation from Intel pro/1000 to AMD PCNet PCI II & III
- upgraded Cisco VPN software from 4.x to 5.x


It seems something related to Virtual Box. The most similar topic I have read is http://www.virtualbox.org/ticket/4499, but no solution is reported.
I do not know how to solve this issue.
Best regards

"Linux Host", "Windows guest": Cisco VPN problem detail

Postby rlbay » 22. Jul 2010, 10:34

Hi, I am providing some details about what I think is a VirtualBox bug.

This is the situation before the Cisco VPN connection is established:

Which Cisco VPN? Is it an SSL VPN?

I would argue that the GUEST behavior is correct.

When I use Cisco (Not SSL) VPN, I can no longer access my local network, I can only access hosts that are on the opposite side of the VPN tunnel.

Hi TonyPh12345,

>Which Cisco VPN? Is it an SSL VPN?
The exact name is "Cisco System VPN Client" actually at version 5.0.07.0290. It is not the SSL VPN Cisco client.

> I would argue that the GUEST behavior is correct.
> When I use Cisco (Not SSL) VPN, I can no longer access my local network, I can only access hosts that are on the opposite side of the VPN tunnel.
The problem is that I cannot reach the remote network! I know that the local network is forbidden, but I am supposed to reach the remote server for which I established the VPN connection. The problem is this one: I cannot reach the server which I supposed to reach. Using a "real" XP, the remote server is available, using che VBox'ed XP, the remote server is not available.

Hi, is there any way to correct the (probable) bug I have reported?
