Interfaces
10. (Optional) Allow all addresses is disabled by default. Toggle on to enable.
When enabled, this option allows forwarding between the source interface and devices
connected to this interface, which allows connected devices to forward and receive packets
without network address translation (NAT). This should normally be disabled unless it is
required for modem passthrough, because some cellular will disconnect modems that send
packets that are not from the carrier-assigned IP address.
11. Ancillary addressing is enabled by default, which provides an IPv4 address to the connected
device when the source address is not available.
a. For Ancillary address/netmask, type the IPv4 address and netmask to provide to the
connected device when the source address is not available.
b. For Ancillary gateway, type the IPv4 address of the network gateway to be used when the
connected device when the source address is not available.
c. Ancillary DNS redirect is enabled by default, which means resolves all DNS requests to
the connected device and redirects HTTP traffic to the device's web administration page.
12. For Server type, select the type of server to use to pass the IP address through to the client.
13. If PPPoE server is selected for Server type:
a. Click to expand PPPoE server.
b. For Service name, type the name of service to offer to the client.
c. For Access concentrator name, type the name of the access concentrator to report to the
client. If no name is provided, the host name is used.
d. For Authentication method, select the authentication method used to connect to the
remote peer.
If an authentication method is selected, type the Username and Password required to
authenticate the remote peer.
e. (Optional) Click to expand Custom PPP configuration.
f. Custom PPP configuration is disabled by default. Click toggle on Enable.
g. Enable Override to override the default configuration and use only the custom
configuration file.
h. For Configuration file, type or paste configuration data using the format of a pppd options
file.
14. (Optional) Click to expand 802.1x to configure 802.1x port based network access control.
The LR54 can function as an 802.1x authenticator; it does not function as an 802.1x supplicant.
a. Click to expand Authentication.
b. Click Enable server to enable the 802.1x authenticator on the LR54 device.
c. Set the Reauth period.
15. Configure IPv4 settings:
a. Click to expand IPv4.
IPv4 support is enabled by default.
b. Set the Metric.
c. For Weight, type the relative weight for default routes associated with this interface. For
multiple active interfaces with the same metric, Weight is used to load balance traffic to
the interfaces.
