How to open ports for teamspeak?

Question

TP Link

Can't open ports for teamspeak server. Previously, there was a d-link router, everything worked well, now I changed it to tp-link, it seems to have set up the ports, but my friend can’t connect, maybe I’m setting something up wrong?

Router: Archer C20

server ip: 178.214.245.133
password: qwerty
Try to connect, maybe a friend screwed up.
