How to swap network interfaces en0 and en1 in OS X?

Question

macOS

Due to the fact that my gigabit network card is defined as en1, it is impossible to enter the AppStore, which is designed only for the fact that the Internet should be on en0 (this is an analogue of eth0 from the Linux world).
On en1, the Internet comes from outside, from en0 the Internet is distributed from the PC further.
How to swap them?

Answer 1

m ... can you give a little more detail? since when did the AppStore (apparently App \ Store.app) become critical through which interface the Internet is connected?

Answer 2

Did you come up with this yourself? In general, the Internet comes to me on the Wealan and everything works:
