REDHAT7 Firewall (firewall)

Start, stop firewall

# Systemctl Start\stop\restart\status Firewalld

Master configuration file:

/etc/firewalld/zones/public.xml

Firewall command:

Open service:

# Firewall-cmd--permanent--add-service=ssh

To close the service:

# Firewall-cmd--permanent--remove-service=ssh

View Open Services:

# Firewall-cmd--list-services

Open ports:

# Firewall-cmd--permanent--add-port=53/tcp

To close the port:

# Firewall-cmd--permanent--remove-port=53/tcp

To view open ports:

# Firewall-cmd--list-port

Port forwarding:

# Firewall-cmd--permanet--add-forward-port=port=81:proto=tcp:toport=80:toaddr=10.0.0.2

(Note: At this time others access 10.0.0.2 81 is access 80) (seemingly restart firewall after the forwarding is gone)

To cancel Port forwarding:

# Firewall-cmd--permanet--remove-forward-port=port=81:proto=tcp:toport=80:toaddr=10.0.0.2

To view port forwarding:

# Firewall-cmd--list-forward-port

# Firewall-cmd--complete-reload (more thorough)
