              Right now the alias is working again and I can't get it to not work. I did nothing but now it is blocking. Sorry, I don't see the error there and will give it a try again in the future. Thanks for your help so far.

                What was rule 181 in that rule set? Inquiring minds want to know!

                  This is a rule that passed the traffic from one client on LAN to my Cable Modem interface:

                      Are you mixing and matching current data with old?

                        Right now the old config works. But I post it anyways:

                          Are the states that you posted citing rule 181 old data or new?

                          We need to be looking at the same rule set as the state table or we are just wasting time.

                            They were the same rule set. I restored the config againto that point. But this time its working.

                            I will try to get the problem up again and post the same things again...

                                    Oh I see that the second host in that Alias (192.168.1.18) also is not working and passes the traffic to WAN! That's new.

                                      Was not blocked. I still maintain you are confused. I have no idea what state things are in, what should be blocked and what is or isn't because you keep saying you are restoring configs, etc. Stick with ONE configuration, detail exactly what you think should or should not be happening, don't click around trying to fix it, and we might be able to find out where the misconfiguration is.

                                            I‘m still at the same config. Now I rebooted and it works again. I will try to reboot and see if the problem reappears.
