AW: debian 10, vm cant connect to the host bridge
someone recommended that i should give br0 the same hardware address as eno2. I did that, and restarted the vm, and it still does not work.
Here is my current host interface config:

bridge + arp
Hi,
this is propably bridge related and not really a xen problem, but it
might help someone:
Some of our domUs are not able to arp. Arp -n show (incomplete), and
doing a tcpdump shows, that on the dom0''s eth0 the arp request goes out,
the response comes in, but on the vifX.0 interface the arp response is
gone.

macvtap and tagged VLANs to the VM
Hi,
I would like to run a network firewall as a VM on a KVM host. There are
~ 25 VLANs delivered to the KVM host on three dedicated links, no LACP
or other things. I have the VLANs 100-180 on the host's enp1s0, the VLANs
200-280 on the host's enp2s0 and the VLANs 300-380 on the host's enp3s0.
To save myself from configuring all VLANs on the KVM host, I'd like to

Yikes! Routing issues!
We switched over from a bordermanager firewall to a shorewall firewall.
Some stuff is not working now.
I realized that I had not created the route for the network that is not
working however once I created it, it still didn''t work.
Most of our network is fine however some pieces are not working.

Openvpn routing problem
Hi,
I posted this question yesterday on the Openvpn mailing list, with no
response, figured I will ask here too. I have been using openvpn for
quite a while, no major problems encountered. Now I need to allow the
server to access the lan of the client, and I can not figure out the
routing. This is what I have after the tunnel is brought up:

Hello Tom,
I am not sure if you can help with this but I am at my wits end.
If you hit this site and do a force refresh (ctrl + F5) the site will time
out
and lose connections.
Do the same on port 443 and it does not time out???
The web site I am reffering to is www.tituswill.com

Can't get cable connection working on virtual router machine
I'm pretty new to KVM and have a KVM CentOS 7.1 hypervisor running a few
VMs. I'm moving all my VMs from an ESXi host as I want to use KVM in
future. Most of my VMs are working except for one which is running a Sophos
UTM router (Sophos UTM is similar to products like pfSense

[Bridge] Error while trying to setup bridge, appears to be a loop
Hello,
I've been trying to implement a bridge in place for a clustered firewall
at one of our office locations. Currently we NAT two class C's
internally. We decided, for performance reasons, that it would make
sense to put our servers into an official DMZ. So we started this
bridging project. Our goal is to have two redundant firewalls in place.
There is no need for active/active.

Problem With Android Configuration
Yes. The problem is lollipop. I tried to install tinc on my brother's
device which mount a cyano 10.1( android 4.2.2) and it works.
I don't understand which is the problem with lollipop. Is there a firewall
that block the packets?

If you are running Lollipop / Android 5.x on your Nexus 5, then you are
probably seeing the same issue I was with it. lollipop seems to change

Hi, I'm not sure what sort of diagram you mean, but I'll have a try. Does
this help? It sounds like I need to do something to enable routing on what
I've labelled "NIC3" on the diagram - can you please explain what I need to
do?
