|Here's my situation:|
1. I am VPNing in to a remote server at my office (using openVPN & their access gateway product, works amazingly).
2. I can't inter-mingle the use of public IP addresses on the internet, it needs to ALWAYS be the office IP.
So what is happening is I have virtualbox running at home, nice little windows xp vm that I have built. I boot er up, connect to vpn and bam I've got the office IP I want rather than the stinky home IP address. I need to roll this out to a couple other people and I don't trust their diligence at connecting to vpn before using firefox/chrome/ie. They may forget and then we'll be back to square one with their personal computer ip address and it was all for not.
SO, I need a way to restrict the VM's network adapter that is providing that access to the local (non-vpn/office) internet to only allow the traffic over the ONE (or just not http/80) port for VPNing.
How the hell can I do this with confidence?
Also, there are other applications that we are using that it is important that they rep the public facing ip of the office network (obtained by VPNing). I would prefer not to use the proxy settings of any apps, just restrict by windows firewall, adapter settings.. I don't know, that's why I'm here.
Thank you for all your help, this place seems like an awesome community that's providing a tremendous amount of support.
