ufw allow rules on multiple interfaces

Revision history
Tags: ufw iptables linux

I was trying to set up some rules on multiple interfaces at once with ufw, but had some unsuccessful attempts. Between

This did not open for outgoing traffic on tun0:

$ sudo ufw allow out on tun0,tun1,tun2 to any
$ echo $-

But all of a sudden I was able to ping out on tun0 with this one:

$ sudo ufw allow out on tun0
$ echo $-

Then to see if my previous tun0,tun1,tun2 wasn’t what I thought it was:

$ sudo ufw allow out on qwerty
$ echo $-

What I learned about ufw
