Title: Destination NAT and Firewall Rules (new) after rules migration
Post by: thebraz on January 23, 2026, 02:29:39 PM
First of all...............upgrade to RC1 succeeded.
Applied all the patches mentioned in the other thread.
All the old rules migrated to new following the 5 steps of the Migration Assistant done.
OpenVPN Instance and port forwarding rules (now Destination NAT) all working (also the ones using Aliases).
Not tried the Shaper yet.

I'd have a question: in the OpenVPN section and in the WAN section of the Rules (new) I find rules that are already present in Destination NAT.
Furthemore if a rule is disabled in Destination NAT but enabled in the WAN section of Rules (new) the thing doesn't work till I enable it in Destination NAT.

I find confusing the apparent "duplication" of rules, could someone please help me clarifyng the function of the two section and why rules are present in both?

Thanks in advance

One rule performs the NAT and the second permits the resulting traffic. With the previous system, it was a NAT port forward rule and a (potentially auto-managed) firewall rule.

I have not tried 26.1RC yet. But I have a feeling, with the way I've set up NAT and FW under 25.7, a straight forward migration will not be possible. For example, the change in the priority of floating rules on single interfaces and the lack of auto/associated firewall rules for port forwards.
