# Test Firewall installation

Test Firewall installation to make sure Firewall is installed and working properly.

 
 

## Before you begin

 
 

You must have enabled Firewall.

 
  
 

## Task

1. Add a rule to block SSH to a particular system. 
  
 <kbd> /opt/McAfee/ens/fw/bin/mfefwcli --fw-rule-add --index 1 --name "BlockSSH" --action deny --direction out --proto tcp --log enable --remote-service 22 --remote-single x.x.x.x</kbd>
2. Violate the added rule by trying to SSH to that machine. 
  
 <kbd> ssh user name@machine IP</kbd>
3. Verify that SSH is getting blocked for that IP in: 
  
 <kbd> /var/log/messages</kbd>
4. Verify your 
 Firewall installation using this log file: 
  
  
 /tmp/enslfw-epo-setup.log
