I started with 6 rules and I created a 7th rule to allow all traffic from my internal network to get out.
Source: Internal Net
Service: Any
Dest: Any
Action: Allow
It created it as #5 even though the Bottom option was selected when the rule was created.
HOWEVER, if I disable the rule using the traffic light, I can still surf the net. Also, iptables -L shows my rule is still in the USR_FORWARD chain at position #5.
I moved it to position #7 (Bottom) using the GUI.
Also, upon disabling the rule (it was #7, at the time) it moved up the list to number 5. I can move it back to the bottom (#7) , but it has no effect in it's status. The Webadmin shows disabled, and iptables -L shows it is at the bottom of the USR_FORWARD chain now.
