Default Multiple VPN

Hi,

I recently setup a box openbsd 4.0 for firewall. Its running dhcp and nat everything seems to be ok. Problem is I cant do multiple VPN connections to my company VPN. I can connect my laptop but on my desktop i doesnt connect. Im using ipcop firewall before and it works for multiple VPN.

thanks in advance for the help.

Are you able to obtain the logs from your company VPN? It almost sounds like your firewall isn't using separate and distinct source ports for each VPN connection being initiated from behind it (aka, your laptop, desktop, etc.)

Also, please be sure and confirm here that you can connect on the VPN via your desktop when not connecting to the VPN via your laptop.

Hello and welcome.

AFAIK, ipcop is a turn-key firewall with IPSec for VPN.

There have been a number of changes to IPSec on OpenBSD since 4.0, which is no longer supported. For example, in OpenBSD 4.1, support for multiple SAs with the same IP addresses was added. I'm not sure what your problem may be, as I'm not an IPSec user, but this may be the root cause of your problem.

Support for 4.0 ended in November of 2007, when 4.2 was released.

The current release of OpenBSD is 4.3, and 4.4 is expected to be released November 1.

The OpenBSD Project only supports the two most recent releases, currently 4.3 and 4.2.

Great!

Please note: As mentioned above, the OpenBSD Project will cease support of 4.2 with the release of 4.4, scheduled for November 1.
