Justin, that SNAT is not what you want. You want something more like 'For traffic from: Internal (Network)'. Refer to #3 through #5 in Rulz.

Hi Justin,

then use SNAT.

Source: Internal IP
Service: desired service
Destination: external server IP
Change Source: Your public IP
Change Service: blank

Hi Justin,

what is the way you want to communicate?

Internal to external or external to internal?

If you want that your internal user can use sftp to an external server a masquerading to your external interface would be the trick plus firewall rule that the internal user can use sftp to the external server.

If it is external to internal you have to make your DNAT rule like this
Source: Any or the external server
Service: desired service (SFTP or HTTP)
Destination: your public IP

Change destination: your internal IP
Chance service: can be blank

Keep in mind if automatic firewall rule is not ticked you have to create one.

When you want to publish a webserver your can use the Webserver Protection of your UTM intead of DNAT.

Hi Justin,

I assume you want a DNAT from your public ip to your SFTP Server.

You can do this under Network Protection -> NAT
