OK thanks, lots to look into there.
What broadcom chipset modem are you using, or would you rate?
Annoyingly, because my original intent was to reduce the time I have to spend as sysop, by googling pfsense and untangle, I somehow quickly got hooked by this guy's article:
Correct me if I'm wrong though, I should have less work to do if I get a super-router with pfsense on it, or even a ubnt router as you suggest (which one would you look at?)
re: BT business smart hub - although I almost definitely want a separate modem and router, I could go down this low cost route (just £8 for postage) but what sort of firewall options does it offer? I hurt my brain trying to negotiate the BT website.
