Hi all, The patch below does four trivial changes and one big change Trivial changes, these are all in br_netfilter.c: - check ar_pln==4 when giving bridged ARP packets to arptables - delete unnecessary if in br_nf_local_in - add more logging for the "Argh" message - add some brag-comments in the file head comment Big change: let {ip,arp}tables see VLAN tagged {I,AR}P packets. This

Hi all!

I had a major HD failure and need to rebuild my host server and the virtual servers that resided on it. I am moving from CentOS 5.6 to CentOS 6.3. I am using the same configuration, as best as I can tell, that was working only hours ago on 5.6 but does not work on 6.3. My guest server can see network traffic on the bridged network device but I cannot seem to interact with it. Iptables turned

Hello! Recently,I¡¯m doing a security project based upon ipv6.I have built up a bridge to support a transparent firewall.(my system is Fedora Core 2,kernel 2.6.5).In this system ,the version of the iptables is 1.2.7,which does not support ipv6(I have tried it).Thus,I download a new version and test it. The iptables functions in bridge mode,but the ipv6 doesn't work well.In the

Hi all, I''m running Xen-3.2 and linux-image-2.6.18 as Dom0 kernel on a VT-x processor. The problem is that broadcast arp who-has packets are not seen in Dom0 kernel. I''ve tried both precompiled debian kernel and compiled latest one from sources as described at http://lists.xensource.com/archives/html/xen-users/2008-01/msg00699.html There is no linux bridge invoked,

Hi, Following the directions for setting up bridged networking in the red hat virtualization guide and libvirt wiki, I set the following kernel parameters to 0 on a RHEL 5.5 server. net.bridge.bridge-nf-call-ip6tables net.bridge.bridge-nf-call-iptables net.bridge.bridge-nf-call-arptables Unfortunately, doing this broke the port forwarding I'd set up for VMs on my NAT networks, e.g.

I have decided to migrate my latest KVM server to CentOS 6.0 and am beginning to get a little frustrated with some issues that worked perfectly in 5.6. Right now I've given up on getting virbr0 and NAT to work, but now I need networking bridging to work, but nothing seems to fix the issue. I have not had much experience with troubleshooting KVM so could really use some pointers on resolving

One of the primary benefits of virtualization and other containers is isolating the applications you run from the base OS. Putting services other

Dear all, Has anyone experienced this whilst running DRBD over eth1 between two CentOS 5.7 servers? eth1 is a private IP address, unroutable. eth0 is the public address. CentOS will reply sometimes once every 3 days or every 14mins~ saying "My public IP is on eth1" to arp requests when it's not, it's eth0. This freezes traffic and causes issues. We've looked at arp*

In the Redhat EL6 virtualization guide ( http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization/sect-Virtualization-Network_Configuration-Bridged_networking_with_libvirt.html ) I read this: # Configure iptables Configure iptables to allow all traffic to be forwarded across the bridge. # iptables -I FORWARD -m physdev --physdev-is-bridged -j ACCEPT # service iptables

I have a CentOS box that acts as a packet filter/firewall with iptables but the box itself isn't able to reach internet : here why : Internet ----- public IP|ISP router|private IP ----- private IP + public IP/32 + public IP subnet/29|my CentOS fw|private network/dmz As you can see my provider gave us a /29 public ip subnet but behind a private IP subnet (192.168.X.X/24 - used for the

Hi, I have the following issue i recently installed a VM with qemu and libvirtd, everything is almost ok. The problem is that i have 5 usable IP address (valid ip address on internet) for eth0, and i want to use one of this IP for my VM (Windows 2008 Standard R2 by the way). I did the bridge between my eth0 and br0, the VM could browse into internet and download patches, etc. etc. I tried
