[ufw] force all traffic through VPN

I am trying to force all my tun0's traffic through VPN but some some reason, the ufw is not working the way I want to.

Below are the commands that I have executed.. I am able to connect to my SSH and NFS server but for some reason that I am unable to understand, I am unable to surf the net.
What am I missing?

Code:
sudo echo "y" ufw reset
sudo ufw logging off
sudo ufw default deny incoming
sudo ufw default deny outgoing

#Force all VPN traffic to tun0
sudo ufw allow out on tun0 from any to any

#SSH
sudo ufw allow out on enp6s0 to ssh_ip_server port XX proto tcp

#NFS
sudo ufw allow out on enp6s0 to nfs_server_ip port xxx
sudo ufw allow out on enp6s0 to nfs_server_ip port xxx
sudo ufw allow out on enp6s0 to nfs_server_ip port xxx

sudo ufw enable

Hi, I have enabled my UBUNTU 9.10 ufw. By default does it let anything through? I would think it allows all outbound originating requests through and allows for their return but it does not allow any inbound requests. Is this how it works? ---------- Post updated at 08:17 PM ----------... (1 Reply)

NAME
netusage -- Display traffic usage statistics about the network SYNOPSIS
netusage [--help] netusage commands [arguments ...] DESCRIPTION
The netusage program interfaces with symptomsd to display and manage network traffic usage statistics. As additional feature of this tool allows for looking up an application or process name using a Mach-O UUID or a PID. NETWORK STATISTICS COMMANDS
The following commands are used to provide different representations of network traffic usage statistics collected on the system. --all-traffic [-p] [-r] [-n name] [-s sortorder] [-d importfile] [-e exportfile] [--unitize] [--compact] [--interactive] [--interval seconds] Display a table listing the total ingress and egress network traffic usage for each application or process categorized by interface. A timestamp of when the first network traffic was observed is also shown. By default, only applications will be shown unless the -p flag is provided. -p Show a list that includes the combination of applications and processes. -r Force a database refresh before showing the list. -n name Only show the application or process matching name. -s sortorder Sort the list according the following available sort orders: t Sort by total network usage. (default) c Sort by cellular interface usage. w Sort by wi-fi interface usage. i Sort by wired interface usage. a Sort by awdl interface usage. e Sort by expensive interface usage. -d importfile Show a traffic usage comparison between the current values and the contents of the file at importfile. -e exportfile Save the current traffic usage values into exportfile. --unitize Show the table values in unitized format (eg. KB/MB/GB). --compact When showing a traffic usage comparison, only list the entries whose values have changed. --interactive Show a traffic usage table that periodically refresh and can be viewed interactively. When an update occurs, the usage value for the application or process that generated network traffic will appear emphasized. You can use the following com- mands to interact with the table. q Quit p Toggles the values between showing raw bytes and unitized format s Change the sort order of the columns r Redraw the screen h Show help Arrow Keys Scroll the list --interval seconds Set the periodic refresh interval to the specified number of seconds. The minimum value is 5 seconds, and the default interval is 15 seconds. (Only valid in interactive mode) MANAGEMENT COMMANDS
These commands are used to manage and reset the collected network traffic usage statistics. --reset-entry [-p] [-n name] Reset the network traffic usage statistics stored for a single entry. Use the -n flag (and optionally the -p flag) to specify the name of the entry. --unitize name Specify the name of the application to reset the network usage statistics. -p Specify a process name instead of an application name. --reset-all Reset the network traffic usage statistics for all the stored entries. OTHER COMMANDS
These are optional utility commands that are available to look up applications or processes. --resolve-uuid uuid Resolve the given mach-O uuid into an application identifier. --resolve-pid pid Resolve the given pid into an application identifier. Darwin May 31, 2019 Darwin
