I am trying to allow ports in firewall for my big blue button coturn server, but when I am running $ sudo ufw allow 49152-65535/udp
I am receiving the following error: ERROR: Bad port.
Can someone explain to me why it is showing that and how to I solve it? I am in a ubuntu 16.04 server
I was using 49152-65535/udp whereas it should had been 49152:65535/udp
