[Summary of question: Rashi explains Rav Huna's statement, quoted by Rav Huna, to be saying that a Jew who takes Ribis from a Nochri is "Yored l'Timyon."
This is difficult to understand. Is it Asur to lend to a Nochri with interest? But the verse says "la'Nochri Tashich!" Furthermore, the Shulchan Aruch writes that it is *Asur* to lend to them *without* interest, and the Rambam writes that it is a Mitzvah to lend to them with interest!]
The Gemara was of the opinion that the Pasuk gives a *Heter* to lend to a Nochri with Ribis, and it is not a *Chiyuv* to lend to him with Ribis. As for the Isur of "Lo Sechanem," since one does not need to lend to a Nochri at all, there is no problem of "Lo Sechanem.
The Rambam and Shulchan Aruch write the Halachah *le'Maskana*. Nevertheless, see Makos 24a, where the Gemara says that it is not a good idea to lend to a Nochri with Ribis lest one become accustomed to it.
