If disabling NAT reflection doesn't help, check for other completely identical rules in your ruleset:
# egrep -v '^#|^[[:blank:]]*$' /tmp/rules.debug | sort | uniq -c | grep -v '^ 1 'That should output only 100% duplicate lines. In my case they were from NAT reflection. If you have some other source, you may need to address it there (e.g. pfBlocker), though most firewall rules won't be identical since they have unique tracking IDs. So most likely this will come from an internally generated rule like NAT reflection or perhaps from a package.

Is that
no nat on [...]rule a manual outbound NAT rule you have?If so, you have two of them, remove one.
Look in
/tmp/rules.debugand find the line(s) for those rules and see what section they are in.Also, once pf is in that bad state you have to reboot to recover. So fix the NAT rule(s) and then reboot.

@jimp I uninstalled all packages and reinstalled them all the same issue so far, the filter reload would fail. I originally had nat disabled I am turning on one to one to see if that changes anything. I don't remember it set to all disabled before this update.

Please post the text and not screenshots. It's making it unnecessarily hard to follow.
Looking at the code it looks like it's from NAT reflection not outbound NAT. Is that a port forward for NTP you have? Is NAT reflection enabled globally or perhaps on just that rule?

@jimp You got it thanks for the help
here is your request this was the original settings, I have tried to delete the one line however it re adds

This is my NAT for DNS and NTP
I force them to use the firewall
This setting has worked for some time now I get time from the firewall no matter what wan ip address a device requests for NTP. I had issues with time being jumped 15-20 mins without this nat setting for NTP, no clue why so I added a rule that let the firewall handle all NTP requests, after that no issues with time jumps

Do you have NAT reflection enabled globablly or on those rules? If so, disable it.

There is also a per-rule option on the individual port forwards. Is it enabled there?

Also your port forward target should really be
127.0.0.1and not192.168.1.1, assuming192.168.1.1is the LAN address of the firewall.Remember: Upvote with the 👍 button for any user/post you find to be helpful, informative, or deserving of recognition!

Firewall rules

@jimp said in Problem with snapshot 3/31 16:19:49:
127.0.0.1
correct to loopback address
filter reload failed at same point as before with loopback address
-
Did you reboot after making that change? Once you get the error you have to reboot to know if it's fixed. Also check and see if those
no nat onrules are still present.Remember: Upvote with the 👍 button for any user/post you find to be helpful, informative, or deserving of recognition!

I have to wait for 2 hours to do a reboot I am at work and the firewall must be up for 2 hours. I have changed the NTP and DNS to use the loopback 127, the no nat rules still show in debug if you delete them they return. Thanks I will reboot at 11:10am
