Checking IP Address in Fortigate Geography-based Filter list

If you have a website and want to restrict it's access only to some specific countries, Fortinet's geography-based filtering would be very handy in that situation. The geographic-based addresses allow you to indicate the country, and the traffic originating or going to this country is logged, blocked or specific filtering is applied. But there will also be a situation when you might want to know if specific subnet is included in a country list or not. The following handy command will help you in that situation.

#diagnose firewall ipgeo {country-list | ip-list | ip2country}

#diagnose firewall ipgeo ip-list India | grep 180.17


which gave the following output:

         180.178.0.0 - 180.178.31.255
         180.179.0.0 - 180.179.255.255
        72.8.180.176 - 72.8.180.187
         180.152.0.0 - 180.175.255.255
       180.178.192.0 - 180.178.255.255
       180.178.128.0 - 180.178.191.255


The result shows the IP ranges containing the exact match of 180.17 in any one of the octet.

Ansible-Playbook to display output of multiple show commands (using stdout_lines with Loop)

 In this playbook, we we'll see how we can get display of multiple show commands in stdout_lines format. We can make use of loops (or with_items) for submitting multiple commands, but debug output with stdout_lines does not gives the formatted result as it would give for single command. So in case of multiple commands, we can debug the output of each command separately in stdout_lines format.

Filtering Routes in BGP using Route-maps and Prefix-list

Order of preference of attributes in BGP The order of preference varies based on whether the attributes are applied for inbound updates or outbound updates. For inbound updates the order of preference is:     route-map     filter-list     prefix-list, distribute-list For outbound updates the order of preference is:     prefix-list, distribute-list     filter-list     route-map NOTE: The attributes prefix-list and distribute-list are mutually exclusive, and only one command (neighbor distribute-list or neighbor prefix-list) can be applied to each inbound or outbound direction for a particular neighbor. Scenario: We own the AS500 and advertising a network block of 192.0.2.0/24 and 180.179.179.0/16 to two different ISPs.

Cisco ASA Active/Active Failover Configuration

Image
Active/Active failover is only available to security appliances in multiple context mode. In an Active/Active failover configuration, both security appliances can pass network traffic. In Active/Active failover, you divide the security contexts on the security appliance into failover groups. A failover group is simply a logical group of one or more security contexts. You can create a maximum of two failover groups on the security appliance. The admin context is always a member of failover group 1. Any unassigned security contexts are also members of failover group 1 by default. We have already seen the configuration for Active/Standby failover in the previous article. This article focuses on how to configure an Active/Active Failover configuration on ASA Security Appliance.
