What licenses are needed on SG135 for basic firewall and web proxy

Hello all,

We have a spare SG135 in our inventory as a backup appliance so that we can do an immediate swap if any production appliances fail. Rather than leaving it sit on a shelf we'd like to purchase minimal licenses that will provide stateful firewall, simple routing, DHCP, and web proxy.

I know we need the 'web protection' license so no issue there.

I'm not sure if we need a 'base' license or if that is free with the appliance.

I don't think we need 'network protection' license yet our local vendor thinks we do.

Please confirm what we need. 'Web protection' license + what?

Thank you.
