Dumb Firewall/Network Lock Question

[CVjP7dXlHH 1]

A maybe quick and probably elementary question:

 

In a Linux Mint Virtualbox installation running Eddie with Network Lock active, do I need to/should I have any additional firewall going?

You provided too little information to answer this question.

A firewall can do various tasks, everything from security (whitelist/blacklist) to connectivity (forwarding/bridging).

What do you want to accomplish?

 

If the goal is making your machine unreachable from outside, that is already done as soon as you connect to the VPN.

If the goal is making sure no traffic can go out bypassing the VPN connection, network lock takes care of that part.

Thank you for the response. What I want to accomplish is to make sure that any and all connections take place through the VPN only. It seems that is specifically what Network Lock ensures.

All you need to do is make sure you have network lock enabled on your host machine and set your VM internet adapter to NAT. That way all traffic will be routed through your VPN connection.
