DHCP- You can push DHCP address to vpn clients but most home routers have a very basic DHCP server that you cant do with this. If you are running something like DHCPD or Windows Server DHCP, im sure there is a way to push them.
Im gonna test this with edgy later on, im sure you will be able to do the exact stuff and have it work
If you are a vpn client and want to use the vpn for your internet, you will need to set a proxy up at your office and point your web browser to it. If not you will continue to browse the internet with whatever connection you have.
There are ALOT more options for openvpn, if you would like to review them check out the site!
