6: Basic Parameters Note: Configurations with the same IP subnet on multiple interfaces (Ethernet or PPP) are not currently supported. Gateway Default IP address of the router for this network. If this has not been set manually, any gateway acquired by DHCP for Eth1 or Eth2 displays. All network traffic that matches the Eth1 IP address and subnet mask is sent out Eth1. All network traffic that matches the Eth2 IP address and subnet mask is sent out Eth 2. If you set a default gateway, any network traffic that does not match Eth1 or Eth2 is sent to the default gateway for routing. DHCP-Acquired Gateway acquired by DHCP for Eth1 or Eth2. View only. GPRS-Acquired Displays the IP address of the router if it has been automatically assigned by General Packet Radio Service (GPRS). View only. Precedence Indicates whether the gateway acquired by DHCP or the default gateway takes precedence. The default is DHCP Gateway. If the DHCP Gateway is selected and both Eth1 and Eth2 are configured for DHCP, the SLB gives precedence to the Eth1 gateway. Alternate An alternate IP address of the router for this network, to be used if an IP address usually accessible through the default gateway fails to return one or more pings. IP Address to Ping IP address to ping to determine whether to use the alternate gateway. Ethernet Port to Ping Ethernet port to use for the ping. Delay between Pings Number of seconds between pings Number of Failed Pings Number of pings that fail before the SLB uses the alternate gateway. Enable IP Forwarding IP forwarding enables network traffic received on one interface (Eth1, Eth2, or an external/USB modem attached to the SLB with an active PPP connection) to be transferred out another interface (any of the above). The default behavior (if IP forwarding is disabled) is for network traffic to be received but not routed to another destination. Enabling IP forwarding is required if you enable Network Address Translation (NAT) for any device port modem or USB/ISDN modem. IP forwarding allows a user accessing the SLB over a modem to access the network connected to Eth1 or Eth2. Hostname & Name Servers Hostname Domain The default host name is slbXXXX, where XXXX is the last 4 characters of the hardware address of Ethernet Port 1. There is a 64-character limit (contiguous characters, no spaces). The host name becomes the prompt in the command line interface. If desired, specify a domain name (for example, support.lantronix.com). The domain name is used for host name resolution within the SLB. For example, if abcd is specified for the SMTP server, and mydomain.com is specified for the domain, if abcd cannot be resolved, the SLB attempts to resolve abcd.mydomain.com for the SMTP server.
