Hi all,

Here is my setup:

Host: PC-BSD 9.0-RC1
Guest: Ubuntu 10.04

I need to connect to outside VPN which I cannot do from PC-BSD, thats why I installed Ubuntu on VirtualBox as a guest.

Currently, I can connect to the VPN I want from guest Ubuntu. What I need is, somehow, use that connection outside guest too. i.e. on my host. So that I can connect to that VPN from PC-BSD itself.

I tried looking at networking options of VirtualBox but cannot figure-out a way. Which mode should I use and how to setup the interfaces?

Apologies if this information is not sufficient. Let me know and I can provide whatever is needed.

Thanks in advance,
hpbsd.

Guest shoulds have 2 legs (2 vAdapters)
1. vNIC1 - (eth0) bridge or NAT (or whatever makes your VPN happy)
2. vNIC2 - (eth1) VBox host-only network.

Host should have 2 legs:
1. eth0 for physical network - disable TCP/IP stack on this one (use 0.0.0.0 as IP)
2. vbox0 - enable TCP/IP on this... it will force your host to route traffic via guest.

Firstly, thanks for getting back.

I've set them up as you said in VirtualBox network config and ifconfig on guest shows this:

I am connected on WiFi and here is how my ifconfig on host looks:

Code: Select all

        ether 0a:00:27:00:00:00

But in this case, I seem to not get any connectivity on the host.

Hmm.. sorry NAT will not work for this case. Only bridge.
NAT uses host's TCP/IP stack, which we disable for your case. Bridge bypasses it, and uses WiFi/Ethernet directly.
Try with Eithernet first (without WiFi) -- WiFi will give you much more trouble. try WiFi later.
Ask BSD dudes if Bridge-over-Wifi is supported on BSD. (On Linux it is)

Guest shoulds have 2 legs (2 vAdapters)
1. vNIC1 - (eth0) bridge only
2. vNIC2 - (eth1) VBox host-only network.

I need to have wireless working.

Another thought in the same direction, since I have VPN working inside guest (ubuntu), can I use port-forwarding somehow to use VPNe'd access in host (bsd)?
