Not sure how to configure Shorewall 2.1.3
I have an access-IProm my isp that I configured my eth0 with.
And I also have an IP-range assigned from my ISP that will be used on my servers connected to eth1. The IP-range is routed thru the access-IP.
This is how my configfiles look like. Internal everything seems to work but not external.

Proxy ARP working from Internet but not from fw and loc
Hello everybody.
I could not find an answer to my problem in the archive. (But that may just
be me :-) )
I have a problem with proxy arp and connection from loc (localnet) and from
the firewall.
Works fine from internet to dmz / proxy arp and vise versa.
I have a feeling the solution is simple, but I''m no guru in Linux routing
etc.
The problem seems to be the routing setup.

3 Interface problem
Having a problem with the 3 interface setup. I can get DMZ hosts, and
FW to see internet, but anything on LOC interface is unable to get
out. My first post to the list didn''t have the information needed,
sorry for that, but thank you for pointing me to more resources. I''ve
looked at the problem myself some more, but am still stuck.

Net > DMZ > AllowFTP
Lables:
Gateway = 209.5.171.65
Netmask = 255.255.255.192
Eth0 = net = 209.5.171.66
Eth1 = loc = 192.168.0.1
There is no NAT clients, in essence loc is dmz. I can rename loc to dmz
if that helps. Proxy/ARP is used for IP addresses 209.5.171.67-126
Problem:
Using the Shorewall Action AllowFTP does not result in desired behavior
when connecting from Internet to machines behind firewall in DMZ. From

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
<https://www.pfsense.org/>, Smoothwall <http://www.smoothwall.org/> etc).
The host has 3 physical NICs

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.

Hi,
Can you show as the config of eno4?
And can you diff the config of eno1 and eno4. Looks like there is a
difference somewhere.

AW: debian 10, vm cant connect to the host bridge
I should have what i want to achive.
The server is intended as a host for VMs. Our network has multiple VLANs, and the VMs will be connected to different VLANS. The interface eno1 is for host traffic and eno2 is connected to the trunk port of the switch, making the different VLANS availabel to the VMs via the br0. I want to use a VLAN-aware br0, so that I specify in my VM config (on the host

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
