@arashnh11 FYI @mario edited his original response to fix it to the correct solution. To repeat his solution (since edits do not trigger an email):

Yes you can set the port range that WebSockify uses, simply modify your cluster configuration like so:

batch_connect:
  vnc:
    min_port: 2000
    max_port: 65535

You can also set the min/max port range in individual batch connect applications as well.

Note the context of this in a full cluster config is:

v2:
  metadata:
    title: "Owens"
    login:
    host: "owens.osc.edu"
  job:
    adapter: "torque"
    host: "owens-batch.ten.osc.edu"
    lib: "/opt/torque/lib64"
    bin: "/opt/torque/bin"
    version: "6.0.1"
  batch_connect:
    vnc:
      min_port: 2000
      max_port: 65535
      script_wrapper: "module restore\nmodule load ondemand-vnc\n%s"
