What is the default policy of PH Firewall?

After an inbound rule has been added to the ruleset, all other packets are dropped by default. To allow inbound traffic to additional ports, you must create additional firewall rules.

Will changes to my PH Firewall interrupt existing traffic?

No. Established connections are left intact. When you change a rule in a firewall group, changes will only be applied to new connections.

Can I apply the same firewall group to more than one server?

Yes, you can use the same firewall group on any number of servers.

PH Firewall is comparable to most firewall programs bundled in with server operating systems. However, PH Firewall has several key differences.

• Packet filtering takes place at a higher level on the network, reducing resource usage of your server.
• The firewall is managed through the PH control panel.
• Updating the firewall policy for multiple servers is quick and convenient.
