(This is *somewhat* of an extension to this question.)
I've come to enjoy (yes, I know) using a VPN for all of my internet usage (specifically Freedome), but I don't have a lot of money to buy subscriptions for every single device. I'd like to just purchase one subscription, install it on a single computer/server, and route all traffic through that LAN proxy. I believe this would have the additional advantage that I can set up a firewall on this machine and protect my whole network.
I'm rather new to network security though, and I haven't tested any of this yet. Is there a better method that could be less of a bottleneck? Or does this sound like a good approach for routing traffic?
Update: In the case of Freedome, it appears that this would be a breach of the usage terms:
If the Software and/or its services are shared through a network or the Software is used to filter traffic at servers, firewalls or gateways, you must have a license for either scanning capacity or for the total number of users whom the Software provides services to. Source: Freedome License Terms
