Table 6-7 Wireless (wlan0) Interface Configuration
Field/Button Description
State Select to enable or disable the interface
Hostname Enter the hostname for the interface. It must begin with a letter or number,
continue with a sequence of letters, numbers, or hyphens, and end with a letter or
number.
This setting will take effect immediately, but will not register the hostname with a
DNS server until the next reboot.
Priority Priority ranges from 0-10. The IP stack will give the interface with the lowest
numerical value highest priority and the highest numerical values lowest priority
when sending data. This setting only applies when the gateway is not in bridging
mode and both interfaces are connected to the same IP subnet.
MTU When DHCP is enabled, the MTU size is (usually) provided with the IP address.
When not provided by the DHCP server, or using a static configuration, this value
is used. The MTU size can be from 576 to 1500 bytes, the default being 1500
bytes.
IPv4 State Select to enable or disable.
DHCP Client Select to turn On or Off. At boot up, after the physical link is up, the SGX 5150 unit
will attempt to obtain IPv4 settings from a DHCP server and will periodically renew
these settings with the server.
Note: Overrides BOOTP, the configured IPv4 address/mask, gateway, hostname,
and domain. Changing this value requires you to reboot the SGX 5150 gateway.
Within Web Manager, click Renew to renew the DHCP lease.
IP Address Enter the static IPv4 address to use for the interface. You may enter it alone or in
CIDR format.
Note: This setting will be used if Static IP is active (both DHCP and BOOTP are
Disabled). Changing this value requires you to reboot the SGX 5150 gateway.
When DHCP or BOOTP is enabled, the SGX 5150 unit tries to obtain an IPv4
address from a DHCP or BOOTP server. If it cannot, the SGX 5150 unit generates
and uses an Auto IP address in the range of 169.254.xxx.xxx, with a network mask
of 255.255.0.0.
Default Gateway Enter the IPv4 address of the router for this network.
Note: This setting will be used if Static IP is active (both DHCP and BOOTP are
Disabled).
Domain Enter the domain name suffix for the interface.
Note: This setting will be used when either Static IP or Auto IP is active, or if
DHCP/BOOTP is active and no Domain Suffix was acquired from the server.
DHCP Client ID Enter the ID if the DHCP server requires a DHCP Client ID option. The DHCP
server’s lease table shows IP addresses and MAC addresses for devices. The
lease table shows the client ID, in hexadecimal notation, instead of the SGX 5150
device MAC address.
Primary DNS Enter the IP address of the primary domain name server
Note: This setting will be used when either Static IP or Auto IP is active, or if
DHCP/BOOTP is active and no DNS server was acquired from the server.
Secondary DNS Enter the IP address of the secondary domain name server.
Note: This setting will be used when either Static IP or Auto IP is active, or if
DHCP/BOOTP is active and no DNS server was acquired from the server.
IPv6 State Select to enable or disable.
