Ubuntu Network Lock Deactivated when Eddie Closed

[ms1SDR4ppBabRSjrP18H 0]

Hi AirVPN forums.

 

I'm using 2.13.6 of Eddie on Ubuntu 16.04 and noticed today that when I close the client (or as happened overnight it crashed) the IPTables firewall rules were reset, and all traffic was allowed!!

 

I definitely only want to allow network traffic when AirVPN is connected.

 

I believe this worked in the past - any suggestions?!

 

Kind regards,

Hello!

 

iptables rules restored when you close Eddie: intended and expected.

 

When Eddie crashes, we can't see how it can modify iptables rules or do anything else. Network Lock is a set of iptables and ip6tables rules, please feel free to clarify.

 

Kind regards

I'm running Mint 18.3 (or 18.2 and 18.1 and so on in the past) in a VM and as happens sometimes the Eddie GUI crashes, but openvpn is still running.  I'll just reboot at this point.

 

When I rebooted in the past the network lock rules were still running because Eddie wasn't shut down properly.

 

But, I've noticed lately that network lock rules are not in place upon reboot.

 

Sounds like I'm seeing the same thing as the OP.

That's expected and intentional. Eddie does not set "permanent" iptables rules, they will not survive a system reboot.

Hello!

 

In case it's of any interest and you don't want to reboot for some reason, you can open the System Monitor go to Processes and search for "Mono" and then "openvpn". Killing both, will enable you to restart Eddie without a hitch. I can't speak to the security of it .

I would just like to mention that the users can proactively protect themselves by closing down via UFW accordingly:  I set UFW (frontend for IP tables) to permanently deny all outgoing and incoming and disable routed and logging.  Now when I initiate Eddie and use network lock the client handles the new tables temporarily leaving only tun0 access to the internet.  When I reboot the next day I have no internet access UNTIL Eddie because again UFW has everything blocked.  This would handle any circumstance where a non-Eddie connection is attempted.  Works without fail on my family machines.  I don't use Eddie's network lock on my other machines because I want to manually control any and all connections.  Part of why I like this configuration is that "family" cannot connect to the internet without going through Air.  Slick and sure fire!
