Title:
Pulse connect VPN exists because unwanted avahi network starts
Status in avahi package in Ubuntu:
New
Bug description:
Pulse VPNs exists very often because avahi enforces network
192.250.0.0/0 over tun0 interface. The message error is:
rmon.error Unauthorized new route to 169.254.0.0/0.0.0.0 has been
added (conflicts with our route to 0.0.0.0), disconnecting
(routemon.cpp:598)
No matter the options to skip avahi on /etc/default/avahi-daemon, it
always calls /etc/network/if-up.d/avahi-autoipd and raises this
discovery network.
A fix can be done patching /etc/network/if-up.d/avahi-autoipd to skip
any tunnel interface.
