Appendix D: Vpn (Site To Site) Example - Microhard Systems BulletPlus Operating Manual

Appendix D: VPN Example (Page 1 of 2)
By completing the Quick Start process, a user should have been able to log in and set up the BulletPlus to
work with their cellular carrier. By completing this, the modem is ready to be used to access the internet
and provide mobile connectivity. However, one of the main applications of the BulletPlus is to access
connected devices remotely. In addition to Port Forwarding and IP-Passthrough, the BulletPlus has several
VPN capabilities, creating a tunnel between two sites, allowing remote devices to be accessed directly.
VPN allows multiple devices to be connected to the BulletPlus without the need to individually map ports to
each device. Complete access to remote devices is available when using a VPN tunnel. A VPN tunnel can
be created by using two BulletPlus devices, each with a public IP address. At least one of the modems
require a static IP address. VPN tunnels can also be created using the BulletPlus to existing VPN capable
devices, such as Cisco or Firebox.
Example: BulletPlus to BulletPlus (Site-to-Site)
Step 1
Log into each BulletPlus (Refer to Quick Start) and ensure that the Firewall is configured. This can be found under
Firewall > General. Ensure that sufficient Rules or IP lists have been setup to allow specific traffic to pass through the
BulletPlus. Once that is complete, remember to "Apply" the changes.
Step 2
Configure the LAN IP and subnet for each BulletPlus. The subnets must be different and cannot overlap.
