There's a few port scanning services around. Since you're now exposed
on the internet, it's well worth checking a few other potentially
exploitable ports.
If it finds any, (1) reconfigure the service to not listen to
connections it shouldn't to, (2) configure your firewall to block them
as well. Point 1 is far more important than point 2, it applies all
the time, the firewall only works when you let it.
