Communicating Across Routers
103
NOTE: You will be able to communicate with the Ethernet Interface from
network stations on different subnets if the print server has been
told about its default router/gateway in the BOOTP response from
the BOOTP server.
Communicating Across Routers
Since Unix environments rely on TCP/IP to communicate with the
Ethernet Interface, crossing routers becomes an issue.
After following one of the Ethernet Interface configuration methods
mentioned (other than the BOOTP method), you will most likely only be
able to communicate with the print server from the same subnet. This
means any host across a router will not be able to see your Ethernet
Interface. In order to communicate across a router, it is best to store a
default router/gateway within the print server so that any packets destined
for another subnet get forwarded to this router automatically. The router
(or series of routers) can then take over ensuring the packets get to their
final destination on another subnet on your network.
To configure a default router/gateway within the Ethernet Interface:
1. Load a Web browser on your Unix station and direct it to the URL
“
http://
EthernetInterfaceIPaddress
/
networkConf.html
” (e.g.
“
http://192.75.11.9/networkConf.html”).
NOTE: If prompted for a “User ID” and password first, type in “
root
” for
the ID and press ENTER at the password prompt since there is
no default password.
2. At the “Network Configuration” HTML form that displays, click in the
first field below the “Gateway” heading and type in the IP address of
the default router/gateway for the Ethernet Interface subnet.
3. Click on the SUBMIT button when done and physically repower the
print server to make sure the new setting is in effect.
