What router / router with access restriction on an open port can be purchased?

Question

network hardware

Good day.
You need a router / router (better a router) in which you can open a port, and then give access to it only to certain IP addresses. Necessary for work (a program is running on a server in one building, in which people from another building also need to work).
Tell me the models of devices with this function.
There is little useful information on the Internet, at best they write that there are such devices, but they do not name specific models.
