Metric
Metric represents the “cost” of transmission for routing purposes. IP routing
uses hop count as the measurement of cost, with a minimum of 1 for directly
connected networks. Enter a number that approximates the cost for this link.
The number need not be precise, but it must be between 1 and 15. In practice, 2
or 3 is usually a good number.
Interface
Interface represents the “exit” of transmission for routing purposes. In this case
Eth0
represents LAN interface and
ppp0
represents GSM/UMTS mobile
interface of the PRESTO Advanced Router.
TCP/UDP Traffic forwarding
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.

Port translation
For incoming data, the PRESTO Advanced 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 PRESTO Advanced 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.
