Pfsense CARP installation and Configuration

Hello Fellas ;

In this section we’ll talk about how to create a cluster between 2 PfSense clients and sychronising them.With this process we’ll prevent any data loss and keep publishing internet to our clients if we face a disaster scenario.

Our enviroment ;

1-) Master system and backup systems’s network legs setting up like this ;

Configuration initialising.

Click on Firewall–>Virtual IPs then click + button to create a virtual network for our WAN interface

Click on Save and then perfom same steps for Lan Network

2-) After this step create a rule for connecting SYN Interfaces each other for both master and backup system

Click on Firewall –> Rule  and create this rule which is below.

After this step it’s time to ping tests to monitorisin both machine’s connections

Ping to 1.1.1.1        à 1.1.1.2 and 192.168.1.1à 192.168.1.2 If there are no any problems we can continue J

3-) Firewall–>Virtual IPs–>Carp Settings to Sync setting for our Master System’s CARP

4-)From Backup machine click on Status–>CARP you’ll see same master systems settings

From Backup machines Firewall –> Virtual IPsàCarp Settings settings like this ;

I’m going to check clients network settings

After this step create a rule on Master Machine you’ll see same rules on backup machines and synchronising done succesfully

5-) Rules that create on video lecture synchronise succesfully you can find logs in this section

In this section we’ll talk about how to create cluster between PfSense hope it’s helpfull.
