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 .
External Syslog Server Setup
By default, only cOS Core's internal memlog feature will capture generated log messages. To send
logs to an external Syslog server, a log receiver object must be configured.
To send logs to Syslog server, first create an IP4 Address object called, for example, syslog_ip
which is set to the IPv4 address of the server. Next, select System > Device > Log and Event
Receivers and choose Add > Syslog Receiver .
The Syslog server properties dialog will appear. Specify a name, for example my_syslog , and
specify the address as the syslog_ip object.
Tip: Address book object naming
The cOS Core address book is organized alphabetically so when choosing names for IP
address objects it is best to have the descriptive part of the name first. In this case, use
syslog_ip as the name and not ip_syslog .
Allowing ICMP Ping Requests
As another example of setting up IP rule set entries, it can be useful to allow outgoing ICMP ping
messages to pass through the firewall. To allow hosts on the internal network G1_net . to send
ping messages to any hosts on the Internet, select Policies > Firewalling > Main IP Rules > Add
and enter the values shown below for the IP policy called allow_ping_outbound . This uses the
predefined service called ping-outbound .
