I am ashamed of myself for not knowing this answer, but to no avail.

I have my router, and behind that several PCs. One of those PCs is an Ubuntu box. If I create a VPN on that, will I be able to connect to all the other PCs, or do I have to have the PCs all stacked behind the Ubuntu, like Ubuntu is a firewall.

My goal in this is to access network shares and remote desktop on my M$7 box. Albeit Win 7 has PPTP built in, I have read where it's not good to run that, but expert opinions here will be taken into account.

router
pc - pc - pc - ubuntu


does it have to be
router
ubuntu
pc - pc - pc

TIA.
