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