Dual SIM Slots

Dual SIM slots provide redundancy and keep the device always online.

Backup and Detachable Antennas

WAN/WISP/Cellular1/Cellular2 give you triple backups for a reliable network. To enhance signal quality, you may replace cellular antennas with extension antennas.

Online Redundancy

Dual SIM slot redundancy and WAN/Cellular backup provide high redundancy for the network.

Band Lock

4G/5G band lock makes it possible to lock the 4G working frequency to one or several bands to maintain operation stability.

(Image for reference. See supported bands in the spec sheet)

TTL Settings

Support manual sets TTL values to meet ISP's requirements. Support set IPv4 TTL and IPv6 HL Values.

Advanced DNS Security

Encrypt your web browsing lookup with trustful partners, preventing eavesdropping and manipulation of DNS data via a man-in-the-middle attack.

VPN Server and Clients

VPN Available in Multiple Ways

Connect back to your company or private network in any way you are used to. Or hold a VPN server to build up your private and secure network. LT12 supports all mainstream VPN protocols, including PPTP, L2TP, OpenVPN, WireGuard, IPSec, and ZEROTIER.
