Configuring IPtables
Before you configure your Verdasys Digital Guardian to forward events, you must configure IPtables in JSA to allow ICMP requests from Verdasys Digital Guardian.
- Use an SSH to log in to JSA as the root user.
Login:
root
Password:
<password>
- Type the following command to edit the
IPtables
file:vi /opt/qradar/conf/iptables.post
The IPtables configuration file is displayed.
- Type the following command to allow JSA to
accept ICMP requests from Verdasys Digital Guardian:
-I QChain 1 -m icmp -p icmp --src <IP address> -j ACCEPT
Where <IP address> is the IP address of your Verdasys Digital Guardian appliance. For example,
-I QChain 1 -m icmp -p icmp --src 10.100.100.101 -j ACCEPT
- Save your
IPtables
configuration. - Type the following command to update
IPtables
in JSA:./opt/qradar/bin/iptables_update.pl
- To verify JSA accepts ICMP traffic from your
Verdasys Digital Guardian, type the following command:
iptables --list --line-numbers
The following output is displayed:
[root@Qradar bin]# iptables --list --line-numbers
Chain QChain (1 references)
