Are you allowed to fast on Chanukah?

No. From the Shulchan Aruch, Orach Chaim 670:1:

ב כ״ה בכסליו מתחילין ח׳ ימי חנוכה ואסורים בהספד ותענית


The eight days of Chanukah begin on the 25th of Kislev, and eulogies and fasts are prohibited on these days.

However, the Aruch Hashulchan states in Orach Chaim 670:6 that a fast because of a bad dream (a "Taanis Chalom" / "תענית חלום") would be permitted:

ובחנוכה אסור להתענות לבד תענית חלום דמתענין אפילו בשבת ויום טוב וצריך למיתב תענית לתעניתו כבשבת ויום טוב


On Chanukah it is forbidden to fast, except for a Taanis Chalom (which may be observed even on Shabbos and Yom Tov). One must then observe an additional fast day in compensation for fasting [on Chanukah], just as is required for Shabbos and Yom Tov.


No. It's the only "Megillat Ta'anit" holiday that was not rescinded.
