In the Control Center, click Administration > Hosts > Configuration.
Under Hostname, check the Scanner whose Ethernet settings you want to modify and click Edit.
On the Edit Host Configuration page, click the Ethernet tab then click the IPv4 tab.
Edit the Ethernet interfaces as needed by entering an IP, netmask, broadcast, and network address for each Ethernet interface.
Change the Scanner or Control Center IP address if needed. You can change the IP address of a Scanner or the Control Center. If you change the IP address of the Control Center, subsequently log into each Scanner's command-line interface. Use the agent-config command to re-allow the secured connection to the Scanner from the new Control Center IP.
Check Enable this interface to activate a second Ethernet interface.
You can dedicate a second Ethernet interface to handling inbound or outbound traffic only.
Add or delete virtual IP addresses to an Ethernet interface as needed.
Under Routing, in the Default gateway field, type the IP address of a default gateway.
A default gateway is required. You must indicate it with an IP address.
To optionally define a static route, under Static Routes, specify the following:
Destination address - IP address, IP address with subnet mask (for example, 126.96.36.199/255.255.255.0), or CIDR notation (for example, 192.30.250.00/18)
Gateway address - IP address
Interface - Default, Ethernet 1, or Ethernet 2
Click Add to add a static route.
You can add up to 50 static routes per Ethernet interface.
You can apply advanced connection settings across all addresses.
