The DHCP server also supports pre-assigning IP addresses to be allocated only to specific MAC addresses and reserving
IP addresses to be used by connected hosts with fixed IP addresses. To reserve an IP addresses for a particular host.
Once applied, devices on the internal network will be able to access resources on the external network.
5.8.3 Port / Protocol forwarding
When using IP Masquerading, devices on the external network cannot initiate connections to devices on the internal
network.
To work around this, Port Forwards can be set up to allow external users to connect to a specific port, or range of ports
on the external interface of the console server/cellular router , and have the console server/cellular router redirect the data
to a specified internal address and port range.
To setup a port/protocol forward:

Navigate to the System: Firewall page, and click on the Port Forwarding tab

Click Add New Port Forward

Fill in the following fields:
Name: Name for the port forward. This should describe the target and the service that the port forward is
used to access
Input Interface : This allows the user to only forward the port from a specific interface. In most cases, this should
be left as "Any"
Source Address / Address Range : This allows the user to restrict access to a port forward to a specific
source IP
address or IP address range of the data. This may be left blank. IP address ranges use the format
ip/netmask (where netmask is in bits 1-32)
Destination Address / Address Range : The destination IP address/address range to match. This may be left blank
IP address ranges use the format ip/netmask (where netmask is in bits 1-32)
Input Port Range : The range of ports to forward to the destination IP. These will be the port(s) specified when
accessing the port forward. These ports need not be the same as the output port range.
Protocol : The protocol of the data being forwarded. The options are TCP or UDP or
“TCP and UDP”
or
ICMP or ESP or GRE or Any
