      No. The state was re-established after you rebooted because a firewall rule passed the traffic.

      DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

        I restored the firewall rules to an earlier date and rebooted the machine. The alias is still the same and now the .17 again gets access. How to find out what rule is the problem?pf1.jpg

          Find the state you think should not be there out of that. Post it.

                            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.

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

                                      @181(1526110841) pass in quick on igb4 route-to (igb5 134.3.212.1) inet from 192.168.1.20 to 192.168.100.1 flags S/SA keep state label "USER_RULE: PC TC4400 Modem"
  [ Evaluations: 946       Packets: 0         Bytes: 0           States: 0     ]
  [ Inserted: pid 41920 State Creations: 0     ]
@182(1417115627) pass in quick on igb4 inet from 192.168.1.0/24 to any flags S/SA keep state label "USER_RULE: Allow ALL IPv4"

                                        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...

                                            OK I've now checked the latest config again and now here are connections to WAN, I'm really confused:
