When I click on the NAT window I can add interfaces to the right column by pressing the button “>>>”. I accidentally added the wrong interface to Nat. I highlight the interface and select “<<<" to remove it from "Nat Enabled Interfaces". The "<<<" button dissapears and I am not able to remove the interface. I have tried everything to remove this interface from "Nat Enabled Interfaces" but it is not working. Must be a bug.
Same trouble, and in iptables list there aren’t the “masquerade” …. ?!
