It seems that Automatic outbound NAT rule generation does not working as expected.
It works only when I define Manual outbound NAT rule generation and create my rules.
Tested with fresh installation OPNsense 18.7.7 and 18.7.7 versions.
Does someone are facing the same problem ??!
Can you define "not working" a bit more for us?
And what does the automatic rule look like, and what is the manual rule?
And after I create a manual Outbound nat rule, my hosts got internet access.
Expected result it is attached.
So you are saying automatic outbound rules aren't created for your LAN anymore since a version 18.7.x? Do you know which particular version for reference?
Yes, the automatic outbound rules aren't created from LAN.
Well, I have tested it 18.7.6 and 18.7.7 .. and both does not work.
I have a 18.7.3 version that is working.
It seems the problem happen after 18.7.5.
We have tested 18.7.6 and 18.7.7 and both have the same behaivor. But with 18.7.5 no.
I can confirm this issue exists in 19.1.x; specifically if you follow the guidance on interfaces page regarding gateway selection for WAN, automatic outbound NAT rules are not created, but manual ones work; if you select the default (only) gateway automatic outbound NAT rules work as expected.
The firewall on which this was diagnosed worked in a n initial test bench situation; the only difference will have been WAN changed to manual from DHCP (and gateway added) and additional LAN/SSN network interfaces added (but not yet in use).
Can't rule out there is still an issue left, but would you mind going through the history and letting me know what differs in your case?
I can confirm this issue exists in 19.1.4. I have updated a v18.7.10 today to v19.1.4 and have no outbound NAT automatic rules and must create it manually.
