Capital gains tax question for sale of house

[CobraGoat]

I believe there is no capital gains tax on the sale of a residence you have resided in for at least two years.

However, if you live in the house for at least two years and then move and rent the former property does the gains tax come back? To avoid, would I have to move back into the house for two years after renting?

If so, any options for avoiding this scenario aside from the obvious?
