Specifications

An example IP pool range might be 196.168.1.10 - 192.168.1.20 with a netmask of 255.255.0.0.
In addition, it is important to specify the Default gateway for the server. This will be handed out
to DHCP clients on the internal networks so that they know where to find the public Internet. The
default gateway is always the IPv4 address of the interface on which the DHCP server is
configured, in this case, G1_ip Select the Options tab to set this.
Also in the Options tab, we should specify the DNS address which is handed out with DHCP
leases. This could be set, for example, to be the IPv4 address object dns1_address.
Syslog Server Setup
Although logging may be enabled, no log messages are captured unless at least one log server is
set up to receive them and this is configured in cOS Core. Syslog is one of the most common
server types.
First we create an IP4 Address object called, for example, syslog_ip which is set to the IPv4 address
of the server. We then configure the sending of log messages to a Syslog server from cOS Core by
selecting System > Device > Log and Event Receivers and then choosing Add > Syslog
Receiver.
The syslog server properties dialog will now appear. We give the server a name, for example
my_syslog, and specify its IPv4 address as the syslog_ip object.
