(Get the code!)
Same problem here. Also when I "ufw enable" then several seconds later networking stops. I have get Ubuntu to gracefully power-down using the power-button and then gracefully power-up.
ufw 0.36
Out of curiosity, is anyone here having this problem wish ufw starting up at boot time while also using having fail2ban installed?
Here is my theory. It takes a while for fail2ban to issue the myriad of iptable commands of the fail2ban database it large. When ufw tries to initialise there may be a clash or lock held either by an iptables instance spawned by fail2ban or an iptables instance spawned by ufw. One of them will fail and will quite probably mess-up ufw's rules breaking network connectivity.
This time I waited for fail2ban to finish establishing its iptables rules before issuing "ufw enable" and this time round network connectivity was not lost.
How to I ensure that ufw is fully up and initialised BEFORE the fail2ban service starts?
