For the push module to work properly on the Local Security Gateway you can use both static and automatic IP addresses. Though for convenience a static IP address is recommended when Local Security Gateway is accessed remotely, this will allow you to locate it on the local network immediately or even create port forwarding rules for remote access.
By default your Local Security Gateway will be set to DHCP (automatic) IP addressing mode.
To assign a static IP address using an SSH shell, the first step is to locate the gateway on your local network. Any IP discovery tool can be used for this, here is an example of a search using Advanced IP Scanner:
Once the unit is identified access it using your preferred SSH client, for example using Putty.
nano /etc/network/interfaces
You should be at a screen that looks like this
(Be sure to insert your own appropriate IP Address, Subnet, Gateway, and DNS)
auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
gateway 192.168.1.1
dns-nameservers 192.168.1.1
#dns-nameservers 1.1.1.1 1.0.0.1
Next, apply new network settings. Either reboot the gateway or type this command:
If you assigned a new IP address to your Local Security Gateway you will lose connection in the current session of SSH and you will need to reconnect the unit using this new address.
