Activate Network Lock causes error

[bitrogue 1]

Hi, on starting Eddie, when I click on 'Activate Network Lock', after the 'Are you sure' prompt then I'm getting the following error

Exception: iptables don't reply, probably kernel modules issue

This has been working fine until recently.
I'm using Pop! OS 21.04 and they recently upped their kernel to 5.15.5, so that may have something to do with it.
I've tried Eddie versions 2.20 and experimental 2.21.3beta and both have the error.

If I avoid the 'Activate Network Lock' and just run 'Connect to a recommended server' then this runs just fine. But then I lose some connectivity to other servers and services across my LAN.

Any thoughts?

That. Actually. Worked!

Fantastic, thank you for the quick turnaround and resolution!

It's strictly speaking not a resolution, you're just using nf_tables instead of iptables now. But as NetLock now works in any case, you're welcome.

I am testing Manjaro and it too requires 'nftables' to be installed. However it is very different compared to debian based systems.

sudo pacman -S nftables                                                                      1 ✘

That should work for Manjaro with pacman instead of apt-get or apt.
