INS: "Are you looking to build a VPN between the cellular modem and another modem, router, or firewall a.k.a. Site to Site VPN or are you looking to VPN to the modem from a computer, phone, or tablet a.k.a. Road Warrior VPN?"
Customer: "Road Warrior. I want to be able to VPN from my laptop and my phone."
And there is the catch. Cellular modems listing VPN on the datasheet are most often referring to Site to Site VPN support only. Road warrior capability is often not supported at all, supported with older insecure technologies, or only supported with additional licensing, subscriptions, and/or overly complicated configuration.
The good news is that Peplink has removed all these obstacles with the addition of L2TP over IPSec support in their MAX Router products. What makes this feature addition so great?
1) L2TP over IPSec is supported natively on all major desktop and mobile operating systems. Whether you're using OSX, iOS, Windows, or Android you will be able to connect using native configuration - no additional VPN client software and associated costs!
3) Peplink's implementation offers one of the simplest configurations we have seen while providing one of the most widely accepted secure VPN technologies. As shown below, you simply enable the feature, add the global/tunnel pre-shared key, configure on which interfaces you want to allow remote connections, and add user accounts.
If you're looking for Road Warrior VPN over cellular, look no further than Peplink MAX routers!
***We've noticed that certain client operating systems (Windows and iOS for example) default to enabling a setting of "Use default gateway on remote network" or "Send All Traffic" in their L2TP setup. This effectively disables split tunneling on the client and sends ALL of the client's traffic (including internet traffic) over the tunnel after which it is sent out over cellular. As this can quickly consume a cellular data plan, strongly consider turning this setting off to enable split tunneling (send only interesting traffic over tunnel and rest directly to destination)***
