I have a customer who's IT company has gone radio silent for months and there SCN isn't working. Not to mention, their IT guy was supposed to get a VPN firewall setup for their remote phones. So it's been sitting on the public network waiting for him to fix this, and now he's gone. I know it's bad, there was a rush to get workers working remotely for Covid and IT was going to fix it. But anyway, they have asked me if I could setup a VPN between the sites and for their remote phones. I'm looking for a device that won't need a yearly subscription but can suite the needs specified. Any recommendations? TIA
