Anyone know if I can set up a tcp and udp listener?

app = “edu-echo”  
primary\_region = ‘fra’

[build]

[http\_service]  
internal\_port = 3000  
force\_https = true  
auto\_stop\_machines = ‘stop’  
auto\_start\_machines = true  
min\_machines\_running = 0  
processes = [‘app’]

[[services]]  
protocol = “tcp”  
internal\_port = 9000  
ports = [{ port = 9000 }]

[[services]]  
protocol = “udp”  
internal\_port = 9001  
ports = [{ port = 9001 }]

[[vm]]  
memory = ‘1gb’  
cpu\_kind = ‘shared’  
cpus = 1  
memory\_mb = 1024
