We’ve recently moved into a new built property and the internet comes through a openreach box in the storage under the stairs.

Someone from the isp told me that i can actually have the router outside if i plugged in the ethernet cable from the openreach box to the port next to it and then the router can be outside on one of the ethernet sockets outside.

My question is, can i draw a cable from the router to the port next to the openreach box and expect to have a connection on the other ports around the house? (Socket right next to tv, want to use the socket but leave the router where it is to keep the TV unit area tidy) will buy some ethernet cables to test it out if its possible.
