OpenVPN Support Forum

I have a server running Windows 2008 R2. And I am running Windows 2003 in VMware on it. I installed OpenVPN on Windows 2008. I can connect with TUN and acsess server. I want to acsess VMware guest (Windows 2003) system over VPN network. Problem is:
VMware cannot use bridged network as adapter. Also VMware visual network adapter cannor bridged with TAP device, because VMware block this operatation (give this info http://vmware.com/info?id=68).

I don't want to install in guest (2003) because of performance.

Is there another option?

Thanks.

If form Win2008 server you can ping the VMware host and use network services, just configure routing on Win2008 as if VMware host is another computer on lan.

Mimiko is right.

I actually use a similar setup myself: my laptop runs Linux, vmware player and openvpn; I run Windows XP as a VM. When my openvpn is set up I can connect remotely to the Windows XP VM using either windows file sharing or using RDP .

It's just a matter of routing

I can't route on win2008. My configuration like this:

I am using tun connection.

Win2008 (Host)
-----------------
TAP adapter: 10.5.0.0/255.255.255.0
Wnet8 adapter (NAT-share host ip adress with host): 192.168.40.1 (DHCP enabled 192.168.40.128 to 255)
routes:
10.5.0.0 255.255.255.0 to 10.5.0.1
192.168.40.0 255.255.255.0 to 192.168.40.1

Win2003 (guest)
----------------
Wnet8 adapter: 192.168.40.137

XP (VPN Client)
----------------------
TAP adapter: 10.5.0.6
routes:
10.5.0.0 255.255.255.0 to 10.5.0.6

I can ping win2003 (192.168.40.137) on win2008.
I can ping 10.5.0.1 and 192.168.40.1 on XP but I can't ping 192.168.40.137

Any advice?
Thanks.

Just add to OpenVPN server config file (on WIn 2008) the following:

Just add to OpenVPN server config file (on WIn 2008) the following:
Code:
push "route 192.168.40.0 255.255.255.0"

plus, inside the Windows VM, add a route
if required (in most cases the 192.168.40.1 host is already the default GW)

I added all. I can't ping 192.168.40.137. I tracert 192.168.40.137 on XP and log like this:

1 775 ms 510 ms 273 ms 10.5.0.1
2 * * * time out.
3 * * * time out.
4 * * * time out.

I think packet cannot pass win2008 to win2003(vm).

And sorry again 192.168.40.1 was another device on XP network. I mistake before.

make sure IP forwarding is enabled on the Win2008 box; normally this is done by setting a registry key and rebooting. Alternatively you can also try this NETSH command

I add win2008 and win2003 ip routing, but not ping anyway. I change some ips and try again. I give configuration and route tables here:

I can ping 10.5.0.1 and 192.168.30.1 on XP (Client)
I can ping 10.5.0.6, 192.168.30.1, 192.168.30.128 on win2008 (Host)

Thanks.

I found my own mistake:

On win2003 (guest) I changed route to
route add 10.5.0.0 mask 255.255.255.0 192.168.30.1

Thanks for yours help janjust and Mimiko.
