Title: Wireguard and Documentation
Post by: bbrietzke on August 30, 2026, 06:36:48 PM
I'm new to OPNsense and got most of the setup handled with the provided documentation and the setup works really well.  The one that that is confusing though is the Wireguard setup.

Step 4a references an *Outbound* NAT, which doesn't exist; I'm assuming it now means **Destination** NAT, but I'm not sure.

Has anyone setup Wireguard on the latest and greatest and can walk me through it? I can't seem to find any accurate documentation that would help.

Thank you!

Outbound is source NAT.

Thank you for letting me know that it's the source not the destination NAT that i need to modify.

Unfortunately, things are still not working.  I have the firewall configured as best as the instructions let me know and can provide screenshots if anybody is willing to help.

Firewall / NAT / Outbound ...it is there, please double check.

You must be living under a rock. If you are current and have done all the migrations, it was replaced by Source NAT.

You are current but have not migrated the Outbound-NAT rules yet.
This is how it should look:

I migrated the firewall rules, but I have lost this part, apologies. There is a guide on hot to perfom the migration?
I am looking, but not yet found.
Thanks.

No apologies needed, it is still optional. Maybe look in Outbound NAT or the migration assistant, I don't remember. But it should be easy, nothing complicated this time.

I was looking on the net for a guide...and I was missing the "migration assistant" exactly a line above the NAT menu.
Thanks.
