Triple-SIM VPN 4G LTE Router-BiPAC 121P 

4G LTE Mobility 
With 4G LTE-based internet connection (embedded 4G/LTE module), users can access the Internet while sitting on anywhere. 

Single Radio/ Triple-SIM 
The Triple-SIM provides failover feature to keep Internet connectivity if SIM loses connectivity. 

Automatic Failover/Failback between 4G/LTE and Gigabit EWAN 
Uniquely embedded with 4G/LTE and Gigabit EWAN interfaces, BiPAC 221P ensures seamless Internet connectivity by featuring superior Failover/Failback functionality between GbE WAN and 4G/LTE. Either wired or wireless connection can be set up as a primary or backup WAN port. When the main WAN interface fails, the secondary WAN interface will automatically back up the connection to ensure always-on connectivity. 

Secured VPN connection 
Supporting comprehensive and robust VPN (Virtual Private Network) protocols including IPSec, OpenVPN, GRE, PPTP, L2TP, BiPAC 221P allows users can establish private and encrypted data transmission tunnels over the public Internet between headquarter and branch offices. With a built-in DES/3DES VPN accelerator, BiPAC 221P dramatically enhances IPSec VPN performance.

Multiple Power Supply Methods 
Support DC power input and PoE PD, flexible fits installation environment. Easy Installation is realized with integrated IEEE 802.3at Power over Ethernet (PoE) support, eliminating the need for separate power and data cables.
