USER MANUAL
GWR Router Series
28
Enable
This check box allows you to activate/deactivate this static port translation.
Protocol
Choose between TCP and UDP protocol.
Destination IP
This field specifies IP address of the incoming traffic.
Destination Netmask
This field specifies netmask for the previous address.
Destination Port
This is the TCP/UDP port of application.
Forward to IP
This filed specifies IP address where packets should be forwarded.
Forward to port
Specify TCP/UDP port on which the traffic is going to be forwarded.
Interface
Select interface where portforwarding is done. Portforwarding from outside
(WAN) interface to inside (LAN) interface is done on PPP, and in reverse
direction on Ethernet interface
Add
Click
Add
to insert (add) new item in table to the GWR Router.
Remove
Click Remove to delete selected item from table.
Reload
Click
Reload
to discard any changes and reload previous settings.
Save
Click
Save
to save your changes back to the GWR Router. After pressing
Save
button it make take more than 10 seconds for router to save parameters and
become operational again.

Port translation
For incoming data, the GWR Router forwards IP traffic destined for a specific port, port range or
GRE/IPsec protocol from the cellular interface to a private IP address on the Ethernet “side” of the GWR
Router.
Settings – Dynamic Routing Protocol
Dynamic routing performs the same function as static routing except it is more robust. Static routing
allows routing tables in specific routers to be set up in a static manner so network routes for packets are set.
If a router on the route goes down the destination may become unreachable. Dynamic routing allows
routing tables in routers to change as the possible routes change.
Routing Information Protocol (RIP)
The Routing Information Protocol (RIP) is a dynamic routing protocol used in local and wide area
networks. As such it is classified as an interior gateway protocol (IGP) using the distance-vector routing
algorithm. The Routing Information Protocol provides great network stability, guaranteeing that if one
network connection goes down the network can quickly adapt to send packets through another connection.

GWR Router RIP parameters (Figure 15).
