4.5.3 Firewall > Port Forwarding
The BulletPlus can be used to provide remote access to connected devices. To access these devices a
user must define how incoming traffic is handled by the BulletPlus. If all incoming traffic is intended for a
specific connected device, DMZ could be used to simplify the process, as all incoming traffic can be
directed towards a specific IP address.
In the case where there is multiple devices, or only specific ports need to be passed, Port forwarding is
used to forward traffic coming in from the WAN (Cellular) to specific IP Addresses and Ports on the LAN.
Port forwarding can be used in combination with other firewall features, but the Firewall must be enabled
for Port forwarding to be in effect. If the WAN Request is blocked on the General Tab, additional rules and/
or IP Lists must be set up to allow the port forwarding traffic to pass through the firewall.
IP-Passthrough (Carrier > Settings) is another option for passing traffic through the BulletPlus, in this case
all traffic is passed to a single device connected to the RJ45 port of the BulletPlus, The device must be set
for DHCP, as the BulletPlus assigns the WAN IP to the device, and the modem enters into a transparent
mode, routing all traffic to the RJ45 port. This option bypasses all firewall features of the BulletPlus, as well
as all other features of the BulletPlus such as COM, VPN, GPS etc.
If DMZ is enabled and an
exception port for the WebUI
is not specified, remote
management will not be
possible. The default port for
remote management is TCP
80.
