[solved] No NAT states in FW->LiveView anymore

[stefan00]

Hi everyone,

No matter what I try, I can not get (the "blue") NAT states in the FW LiveView (anymore).

NAT itself works!

Unfortunately, I can not break down since when this happens because I usually have most NAT logging off (except for VPN stuff). So this Post goes into the 24.7 forum, but it could be an issue since a while ago.

I came across the issue when playing a bit with NPTv6 - same thing. Nat states not visible.

tried:
- switching from Hybrid to Manual NAT, generating a Rule and enable Logging
- turning on FW->Settings->"Log packets matched by automatic outbound NAT rules"
- enable/disable FW-settings->"Disable automatic rules which force local services to use the assigned interface gateway."
- switched from business edition to latest Community edition for testing

some specs:
- using VLANS
- OPNsense 24.7.8-amd64

Does anyone have an idea on where to start looking? The problem sounds pretty crazy to me.

best & thanks,
stefan

I guess I found some starting point to the issue:

It seems that in FW->Diagnostics->States->Rules the NAT rules are present (and logged?). At least that's my understanding of this table.

In the FW->Logging->LiveView table, the NAT entry is present but 1) has no rule label displayed 2) is labeled pass(green) instead of NAT (blue)

Log sequence with hybrid NAT rules enabled:






With manual NAT rule:





both cases actual do the correct NAT. But for debugging purposes, it would really be nice to see the them in the FW live log.

Am I completely wrong here, did something change, is this behavior expected or indeed a bug/issue?

@Franco would you mind taking a quick look?

  I was looking only in opnsense/core for the issue

thank you

Hehe yeah sometimes these issues can be spread across multiple different repositories. It is a bug in pf so its in src.

Thanks for spending all the time on your initial post with all the screenshots.
