I have a spare Watchguard 5 series firewall that is up for sale.

I set one of these up at home with pfsense installed and it works great. I use it only for basic content filtering, but there is loads of options with the pfsense OS.

This watchguard no longer has an active Watchguard subscription, but you can use it still as a firewall without any content filtering.

Info on installing pfsense on the watchguard:

Location is Hamilton, can deliver in Hamilton or ship at buyers expense.

Looking for offers around $150

(I'll post some photos this evening)
