Firewall Zone
Determine whether your network interface should be protected by a firewall. For
details, refer to Section "Configuring the Firewall"
Device Activation
Depending on which applications or scripts you use to control your network devices,
set the appropriate start mode. For details, refer to
(page 584).
MTU
Set the maximum transfer rate (MTU) of your interface. Normally, you can safely
leave this setting empty and run with the defaults. Only change this value if your
setup explicitly requires it.
Configuring IP Addresses
When possible, wired network cards available during installation are automatically
configured to use automatic address setup, DHCP.
NOTE: IBM System z and DHCP
On IBM System z platforms, DHCP-based address configuration is only supported
with network cards that have a MAC address. This is only the case with OSA
and OSA Express cards.
DHCP should also be used if you are using a DSL line but with no static IP assigned
by the ISP. If you decide to use DHCP, configure the details in DHCP Client Options.
Find this dialog from the Address tab by selecting Advanced → DHCP Options. Spec-
ify whether the DHCP server should always honor broadcast requests and any identifier
to use. If you have a virtual host setup where different hosts communicate through the
same interface, an identifier is necessary to distinguish them.
DHCP is a good choice for client configuration but it is not ideal for server configuration.
To set a static IP address, proceed as follows:
1 Select a card from the list of detected cards in the YaST network card configura-
tion module and click Edit.
2 In the Address tab, choose Static Address Setup.
