IP Passthrough
In IP Passthrough mode, the AirLink gateway passes the WAN IP address to the selected LAN interface or device.
Note: IP Passthrough is only available on the WAN cellular interface.
IP Passthrough
Rev 1 Dec. 17
Description
The physical interface port or VLAN ID
The IP address of the AirLink gateway for the specified interface port. By default, this is set
to 192.168.13.31 for Ethernet and 192.168.14.31 for USB/net.
Subnet mask indicates the range of device IP addresses that can be reached directly.
Changing this limits or expands the number of clients that can connect to the AirLink
gateway. The default of 255.255.255.0 means that 253 IP addresses can connect to the
AirLink gateway. Uses 192.168.13. as the first three octets of the IP address if the gateway
IP is 192.168.13.31.
Note: Do not use the same IP addresses/subnet mask for WAN and LAN connections.
For example, you cannot have 192.168.13.0/24 as a LAN subnet if the WAN the gateway
is connecting to is using 192.168.13.0/24.
Appears if the interface is configured to allow connected device(s) access to the Internet
Note: Internet access cannot be disabled for Ethernet hosts.
Indicates whether or not the interface has a DHCP server enabled to provide dynamically
allocated IP addresses provided to connected devices
Note: The DHCP server can only be disabled for Ethernet and VLAN.
Ethernet DHCP pool starting IP address (DHCP low address)
The ending IP for the interface (DHCP high address). If the starting and ending IP are the
same, there is a single address in the pool and only one connected device receives an IP
address from the DHCP server for that interface. Some interfaces, such as USB, can only
have a single device connection. For others, statically assigned IP addresses in the same
subnet, but outside of the DHCP pool, can still connect and use the gateway in the same
way as a DHCP connected device.
Select the interface that will be used for IP passthrough. Options are:
Disabled—Private IP addresses are used (default)
•
Ethernet—Ethernet interface is used for IP passthrough
•
USB—USB interface is used for IP passthrough
•
Serial DUN—Serial DUN interface is used for IP passthrough
