8.1, Is nat already running?

[sdad]

Release 8.1, used the downloaded cd to install, no fancy tricks, straight default, selected to make installation a gateway.

In /etc/rc.conf I have

gateway_enable="YES"

. I read that this turns on nat, however, the the manual goes through a complete setup including additional lines in /etc/rc.conf, which I currently do not have.

31.9.5 System Startup Configuration

To enable firewall and NAT support at boot time, the following must be in /etc/rc.conf:

gateway_enable="YES" (1)
firewall_enable="YES" (2)
firewall_type="OPEN" (3)
natd_enable="YES"
natd_interface="fxp0" (4)
natd_flags="" (5)

Is nat running as I currently am configured (the gateway-enable line be itself? Setting up a test network to find out would be extensive, is there a different way to test? Would I be wise to include the additional lines in the /etc/rc.conf even if it is already up and going, or do I risk a conflict somewhere?

I will be adding in the firewall lines for ipfw after verifying that my PPPoE routing is working. Not adverse to typing, but I don't want to break something.

No, this turns on routing. This will make it possible to route traffic between interfaces. It does absolutely nothing to the packets.

Breaking stuff is how you learn
