‘Single Address’ Type for Host2LAN 
Connection

Typically, AirLink gateways/routers are configured to use LAN2LAN VPN 
connections, which allows the AirLink device and its client devices to access the 
VPN tunnel.

However, if the AirLink device must be configured to use a Host2LAN VPN 
connection (where only the AirLink device can access the tunnel), the device 
must be configured to use the “Single Address” local address type, and the 
address must match the device’s USB IP address or Ethernet IP address to 
establish a tunnel to the ACM.

1.

Check and update (if necessary) the IP address that will be used:

·

USB IP address:

i.

In ACEmanager, select LAN > USB.

ii.

In USB Device Mode, make sure USBNET is selected.

On the AirLink device:

Configure the device to use only DH2 
or DH5.

On the ACM:

Configure the peer to use only DH2 or 
DH5.

Make sure the dh-group is configured 
in esp-group proposals
