245U-E Wireless Ethernet Modem User Manual
Rev Version 2.24
The command used in Figure 98 is “arp -a”. It shows the PC’s IP address (like the previous ipconfig
command). In this case the IP address is still 192.168.0.17. It also shows the IP address and associated MAC
address of any another device that has a connection to it.
The command “arp -?” lists the commands available for this function.
route
The “route” command is used for the router function. This is where you are joining two different networks
together via the 245U-E. Refer to “1.1 Getting Started Quickly” for details.
Normally the 245U-E will only accept one routing rule, by using the default gateway IP address on the
Main Network page. If more than one routing rule is needed (for example, for multiple networks each with
a different IP range), a routing table is required. In the example in Figure 99, a routing rule needs to be
entered into the Network A’s PC which will allow access between Network A and Network B. This can be
entered at the command prompt using the following instructions.
• route PRINT will show all active routes on PC.
• route ADD will add a routing table to network.
• route DELETE <destination netmask gateway interface> will delete the unwanted routing table.
• route CHANGE modifies an existing route.

An example of a routing table is shown for the configuration below.
