Why doesn't the Untangle Server's Firewall have rules enabled by default?

• When the Untangle Server is your router, it is performing NAT. NAT protects you from most threats.
• When the Untangle Server is a bridge, the Untangle Server is already behind a firewall. A firewall protects you from most threats.

Can I have a firewall and still use NetMeeting?

Yes. However, on the Untangle Server, you need to pass specific protocols and open specific ports as outlined in Firewall. A Microsoft article, How to Establish NetMeeting Connections Through a Firewall, explains which protocols to pass and which ports to open.

How do I identify unsecure ports?

There are free programs on the Internet that identify unsecure ports. To learn about one, go to Protecting Your Network by Securing Ports.

We currently have a firewall, which lets us do port mapping. I don't see that feature in your Firewall. Will you be adding it, or is there an alternative?

Port mapping (redirection) is a feature of the Router.

I want to lock-down my network but for a few exceptions. What is the best way to do this?

You can set the default behavior to block, as discussed in Firewall. Then, create a few rules to pass.
