+=== Firewall ===
 If your server-machine has a firewall turned on (as NixOS does by default, for instance), don't forget to open appropriate ports; e.g. for NFSv4:
 <syntaxhighlight lang="nix">
 networking.firewall.allowedTCPPorts = [ 2049 ];
+</syntaxhighlight>
+Many clients only support NFSv3, which requires the server to have fixed ports:
+<syntaxhighlight lang="nix">
+  services.nfs.server = {
+    enable = true;
+    # fixed rpc.statd port; for firewall
+    lockdPort = 4001;
+    mountdPort = 4002;
+    statdPort = 4000;
+    extraNfsdConfig = '''';
+  };
+  networking.firewall = {
+    enable = true;
+      # for NFSv3; view with `rpcinfo -p`
+    allowedTCPPorts = [ 111  2049 4000 4001 4002 20048 ];
+    allowedUDPPorts = [ 111 2049 4000 4001  4002 20048 ];
+  };
