Public bug reported:
I use openconnect / network-manager-openconnect to connect the VPN for
work. In Ubuntu 17.04, this worked perfectly fine and I would remain
connected for hours on end, without fail.
Since upgrading to 17.10, however, at least once an hour all traffic
suddenly halts and the network becomes unreachable. Running "ifconfig"
from the terminal shows something like this:
vpn0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1406
inet XXX.XXX.XXX.XXX netmask 255.255.0.0 destination XXX.XXX.XXX.XXX

(UNSPEC)
RX packets 537872 bytes 385640344 (385.6 MB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 426702 bytes 82214569 (82.2 MB)
TX errors 0 dropped 7071 overruns 0 carrier 0 collisions 0
the "dropped" column of TX errors continuously increases when I try to make any
outgoing requests. No incoming data comes in, at all.
I have not been able to isolate specifically what's causing this and
I've not been able to reproduce it intentionally beyond just "connect to
the VPN and use it until it breaks". Non-VPN internet works fine.
Connection is over a hardwired ethernet connection, onboard NIC. (Dell)
