I have a setup with two Internet providers. One circuit (net0 == eth1) is used primarily for employees and tunnels to other sites. The other (net1 == eth2) is for the production machines that customers access. Everythung works in teh sense that packets get to where they are sent (mostly) but I recently I had a sniffer on the system and noticed a problem I cannot solve. traffic coming in

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. dom0# tcpdump -ni eth0 arp who-has 10.32.2.51 tell 10.32.7.70 arp reply

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. [Net] - [Shorewall] - [LAN] - [Cisco] - [Clients and servers not working] The firewall

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 hand the entire

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.

Hello Lartc Mailing List: Been working on something the last week and a half and ALMOST have it working.., just need a few pointers from the wizards on this mailing list to nail it. Ok, my setup is a hub and spoke arrangement, hub is Cisco 2821 with IOS 12.4. Spokes are ruggencom RX1000 routers, Debian based with the following versions installed: rx1000test:~# uname -a Linux rx1000test

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: ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft

Goodday, First my network layout: dsl router (10.0.0.99) | server (eth0 10.0.0.1, eth1 10.0.1.10) | 3 times windows machine (10.0.1.2, 10.0.1.3, 10.0.1.4) (all with proxy settings 10.0.1.10:8080) Now on the server is mandrake 10 installed with shorewall as firewall. And a apache webserver (and no ftp server). When i turned internet sharing on it started squid which added a line in the

Hello Tom, I''ve been using Shorewall for years without problems. My previous version of shorewall was 1.4.6b-1. Everything worked just fine. Today I upgraded using rpm to 2.0.8-1. After update no one can connect to any interface from net. Server can connect to outside world fine and those described in routestopped have no problem connecting. Any help correcting this problem would be

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: SERVER (A.A.A.A) Arx:~# ip addr ... 3: eth1:

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

My Shorewall installation was working great until yesterday when it started logging ''REJECT'' to packets that tried to cross the firewall to the internet. I tried to work past the firewall by entering "shorewall clear" but I still can''t get past the gateway / firewall machine. Does this mean the NIC is damaged? When Shorewall is running I can navigate

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? Andrea Squeri 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
