Yes, there's no way around it: if you run Galene behind a NAT, you need
something outside of the NAT to establish communication.

Are you allowing unrestricted outgoing UDP traffic from the Galene
container?  If you don't, then all of the traffic will be routed through
the TURN server, which will cause load on the TURN server and increase
connection establishment delay by two seconds.

If you do allow unrestricted traffic from Galene the Galene, then your
solution is pretty good.  However, it requires setting up an external TURN
server, which I feel is more hassle than just running Galene directly
exposed to the Internet.

You should have no problems (as long as you're allowing unrestricted
outgoing UDP).  There's a slight increase in connection establishment time
due to the STUN exchange with the TURN server, but it should be
