Doesn't work. I redirected all my errors to /var/log/messages, so here's
what I get when I try to connect Filezilla to that server.

Don't specify GATEWAY in interface files where it isn't used. This
should be set on eth0 only.

Completely isolating P2P/BitTorrent traffic
Hi all,
I''m tring to isolate P2P traffic, specifically BitTorrent, for my QoS
scripts. I can''t seem to completely isolate ALL BitTorrent traffic.
I identify & mark packets and then use tc filters to put them into
appropriate classes. My firewall rules (below) do the markings. My VoIP
boxes'' and ICMP traffic get highest priority (mark 1). Then comes DNS, SSH,

Broken br0
Hello,
I wanted to get an extra IP on my local NIC, so I ran `sudo ip addr add
192.168.1.130/24 dev enp4s0`. This didn't work as intended, so I thought
I'd restart the Ubuntu system to have things back to how they were.
Alas, this didn't happen. While the host still has network as usual, none
of the VMs are able to get a DHCP lease from the router, or any
connectivity at all.
I can

Fixing to bite the dust?
I've been getting LOTS of messages like the below in the daily log, and
from all indications, it appears to all be related to the cpu;
the machine is just over a year old, and was the old vortex.wa4phy;net

lots of other fluff, numerous problems of other nature have started
cropping up. Anyone have any suggestions as to

hosted VMs, VLANs, and firewalld
I'm looking for some information regarding the interaction of KVM,
VLANs, firewalld, and the kernel's forwarding configuration. I would
appreciate input especially from anyone already running a similar
configuration in production. In short, I'm trying to figure out if
a current configuration is inadvertently opening up traffic across
network segments.
