# Test Firewall installation

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

You must have enabled Firewall.

1. Add a rule to block SSH to a particular system.

`/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`
2. Violate the added rule by trying to SSH to that machine.

`ssh user name@machine IP`
3. Verify that SSH is getting blocked for that IP in:

`/var/log/messages`
4. Verify your Firewall installation using this log file:

`/tmp/enslfw-epo-setup.log`
