Indeed, when you restore a config it will reinstall any packages referenced in it. But that shouldn't be a problem as long as you have a valid WAN connection.
@wizardofwhere I think you have the pfsense plugged into the wrong place. I would have modem, to pfsense wan, pfsense lan to switch, vpn is going to take some work because that also needs wan access. You probably need the linksys plugged into same switch and rules on the pfsense to forward traffic for the vpn.
