DNAT over same VLAN TIMEOUT

Good morning,

In our company we have the router RouterBOARD 3011UiAS with a domain pointing to our domain. We have separated the departments with different VLANs, and on the router we have configured DNAT to be able to externally access the host of each developer.

When I try to curl the domain + port (dnat different vlan to mine) it works correctly.

But when I try to do the same on my host, the process returns timeout. This happens with all the teams of the vlan in which I am.

How can I get the router to resolve my DNAT over the same VLAN that I am in?

Thanks
