nordvpn issue

[caiotizio]

i'm running linuxmint 21.1. when nordvpn is up warpinator isn't visible to other lan devices. nordvpn is set to whitelist the local subnet. other apps works fine. warpinator get the vpn server ip instead of local one.

i found how to change the connection interface but still doesn't connect

Same issue here. When connected to nordvpn, Warpinator will eventually discover devices but will not connect to them, showing "Waiting for two-way connection" and "Unable to connect" repeatedly. Devices are on the same network and can ping each other. Disconnecting from the VPN fixes the problem. Interestingly, when file transfer is already running, you can connect to nordvpn and the transfer will continue.

I found a simple workarond that allows you to use Warpinator without disconnecting the VPN:

# Create a group called warpinator
sudo addgroup warpinator
​
# Add yourself to the group
sudo adduser $USER warpinator
​
# Create iptables rule for the group that overrides nordvpn rules
sudo iptables -I OUTPUT 1 -m owner --gid-owner warpinator -j ACCEPT
​
# To run warpinator, execute:
sg warpinator -c warpinator

Now go to Preferences → Connection and select your intended network interface to use.
